S23 preorder ****

On the 27th of February I recieved an email from Samsung stating that I would recieve a R2000 Samsung online store voucher if I preordered the S23. I did so on the 28th of February and my device was delivered a few days later. I was contacted by someone from the online store and I asked when would I receive my voucher since it wasn't in the Samsung members app as stated in the email. I was told I will receive it shortly. It's over a month later, after numerous phone calls to Samsung spanning over an hour in total and still nothing yet. I was told I would recieve the voucher in the email and by your sales representatives and still nothing. Misleading and really bad service
