How to Reach Us
We try to keep contact options simple. Pick the most relevant one.
General support
Email: [email protected]
For account questions, routing or scenario help, or anything where you're not sure where to send it.
Billing, refunds, and cancellation
Route the following inquiries to [email protected] with the subject line that matches your situation:
- "Cancel subscription" — to cancel a Paid Plan. You can also cancel directly through the Paddle customer portal accessible from the in-app billing page (
/billing). See Terms §7b for cancellation rules. - "Right of withdrawal — refund request" — for EU/UK consumers exercising the 14-day right of withdrawal; see the Refund Policy §2.
- "Erroneous charge" — for duplicate transactions, charges after a confirmed cancellation, or other billing-system errors; see the Refund Policy §5.
- "Service-quality dispute" — for systemic service failures during a paid period; see the Refund Policy §6.
- General billing or subscription questions — any other billing-related inquiry.
Paddle as merchant of record. Paddle.com Inc. is the merchant of record for paid subscriptions and is the entity that issues invoices, processes refunds, and handles VAT/sales-tax in 30+ jurisdictions. For invoicing-specific questions that require Paddle's involvement (e.g., reissuing an invoice with a corrected billing entity name, downloading historical invoices outside the Paddle customer portal), visit paddle.com/help. CallPing handles substantive refund decisions; Paddle handles the mechanical processing back to your original payment method.
Security issues
Email: [email protected]. See the Security page for full vulnerability-disclosure scope, in-scope and out-of-scope items, response-time targets, and our safe-harbor statement for good-faith researchers.
For suspected vulnerabilities, exposed credentials, or any other security-sensitive report.
Privacy and data requests
Email: [email protected] (or [email protected] marked "Privacy request" if you prefer the general support address — both reach the same triage workflow).
For exercising rights under GDPR, UK GDPR, CCPA, the Law of Ukraine "On the Protection of Personal Data," or other applicable data-protection law (access, deletion, rectification, portability, objection, opt-out of sale/sharing). See the Privacy Policy §8 for the full list of rights, identity-verification process, and statutory response times.
Reporting AUP abuse
If you believe a CallPing user is violating the Acceptable Use Policy — for example, you received an unsolicited automated call you believe was placed via CallPing — report it to [email protected] (or to [email protected] marked "Abuse report"). Include the time of the call (with timezone), the caller-ID number, and a short description of the call content. See the AUP "Reporting Abuse" section for the full report template.
Mailing Address
The Service is operated by:
- ФОП Даценко А.В. (A.V. Datsenko, sole proprietor registered in Ukraine)
- РНОКПП: 3339403456
- Country of registration: Ukraine
- Mailing address: Plytkova str. 65/106, Kharkiv, Kharkivska oblast, 61047, Ukraine
EU/UK/UA consumer-law identification requirements (GDPR Article 13(1)(a), EU Consumer Rights Directive Article 6(1)(c), UK CRA 2015) are met by this published mailing address together with the operator block above and the email contacts in the sections above.
Response Times
CallPing is a small team. The targets below are operational commitments, not contractual SLAs unless you are an Enterprise customer with a separate written contract.
| Request type | Target |
|---|---|
| General support inquiries (account, routing, scenarios) | Best-effort within 2 business days |
| Billing inquiries (cancellation, refund, erroneous charge, service-quality dispute) | Best-effort within 2 business days |
| Security reports via [email protected] | Acknowledgement within 2 business days; initial assessment within 5 business days for credible reports (see Security page) |
| AUP appeals (suspended/terminated account contesting the action) | Best-effort within 5 business days (see AUP "Right of Appeal") |
| Statutory data-protection rights requests (GDPR / UK GDPR / Ukrainian law) | Within 30 days, extendable by a further 60 days for complex requests with notice (see Privacy Policy §8) |
| Statutory data-protection rights requests (CCPA / CPRA) | Within 45 days, extendable as permitted by law |
The 2-business-day general-support target does not apply to statutory data-protection requests — those run on the longer GDPR / CCPA timetables above, with the identity-verification step described in the Privacy Policy. Enterprise customers with a commercial SLA receive response-time commitments per their contract.
