Voucher refund- The voucher or code for flook was F-9a8baba70-R

In August 2021 I bought a voucher through Vodacom which was to be redeemed at Flook for sneakers however, the type and size I wanted was not available. I then asked for a refund. Since August 2021 up until 23 March 2022, the refund is still not effected. I have share all kinds of information like voucher number, date bought, bank details where i paid the voucher from, bank details where the refund should be paid in.... all kinds of excuses that vodacom could come up with happened, they are in backlog, there is not enough staff, etc. I send many messages to ***, Specialist customer relations Officer... *** but nothing up to now came forth. I have 3 cell phones contract with this same company that does not respect customers.
