No correspondence as to voucher

I bought a voucher via standard bank ATM deposit on my new cellphone number *** on the 20-07-23 at 17:14 to be exact as I didn't receive my voucher I asked my brother who was visiting me at the time to email acoin support and ask the what's happening they then eventually told him to send proof of payment proof of identity and proof of the number belonging to me in the meantime I contacted mtn to try and see why I don't get sms's then they realized that the same number was assigned to 2 different sims an that ,that's the reason for nothing going through as it is a faulty number at the end of the day I can't retrace anything on that number as it is completely blocked and a sim swop is to much trouble if one will be able to.so I did send them the welcome message from mtn with my new number as confirmation in the message and copy's of my id and the slip from the standard bank ATM once your cash deposit is successful....to see if the can maby E-mail me the voucher cause they said it was send to that number surly they can check and see that that vouchers haven't been used as the message was never delivered to my phone and I'm yet to receive any correspondence.....what makes me angry that this is the 3rd voucher in less than 1.5 months it seems like there's a problem that needs to be addressed. First my company phone number then on my son's number and now on my new number it's starting to show a pattern of refuseing to pay vouchers even if the customer have the legitimate proof....I hope the wake up and sort out this unnecessary time waisting
