Cancellation & refund policy
Last updated: 8 September 2026.
1. Credits and trial
Unused purchased credits remain available when a number or project is deleted and do not expire monthly. The free trial expires one week after the first successful connection and has no monetary refund value. There is no automatic renewal. Review the selected pack and this policy before payment.
2. Requesting a refund
A refund for an unused pack may be requested within 7 days of purchase. If some credits have been used, the request is reviewed according to usage and any costs incurred by the service.
3. Service failures
If we cannot provide the service because of a fault on our side, we may restore affected units or offer an appropriate refund. This does not include delivery failures caused by an invalid number, channel-provider refusal or a customer policy violation.
4. How to request
Send your payment reference, account email and reason to support@mz3b.com. Refunds are processed through the original payment method within the payment provider’s processing timeframes.
5. Disputes
Please contact us first to resolve the issue. This policy does not limit mandatory rights under applicable law or the Merchant of Record’s terms.
