Tymebank and 1 Voucer *****

Terrible Service. I recently bought a Roblox Voucher for my son and was sent a voucher which was invalid. I was then Directed to 1Voucher which is in partnership with Tymebank and a month later I have not had any feedback. After repeated phone calls amounting to almos an hour or more I have yet to be helped. The customer service agents at Tymebank neer sents the request for the proof of the conversation or the call log when you ask them . I would like feedback and help with this issue or they can refund me. As this is proving to be very ****my as both these companies never take ownership of the issues of calls. All emails sent back and forth with no resolve do not even have a signature of the person dealing with the issue
