TalkRand says that a verified technical failure preventing access to purchased credits or a subscription can qualify for a refund review.
If you still cannot access the service, contact [email protected] or use TalkRand’s billing inquiry form, providing your account email, payment date and amount, the last four digits of the card, and a description of the access problem.
Ask them to restore your paid access or review the charge for a refund if the service cannot be restored.
