TFG took my R1000 but can't furnish my voucher

I purchased an eGift Card / eVoucher for R1000 on 6 Jan but never received an email or SMS despite having provided the correct information. I have the slip to prove this.

I had to return to Menlyn 5 times to try and resolve the issue. The relevant store called customer service on my behalf and tried to have them either resend the SMS or cancel and refund the voucher. It was all in vain because I still haven't received the voucher and customer service informed us that a voucher cannot be refunded.

When we dealt with customer service, we experienced really bad service. In one instance Leamma/Lehama told us that her system was going to disconnect the call and that we had to call back later. The staff at the store where I was immediately called the customer service team again and was informed that Leamma/Lehama went to tea (her system was never going to end the call). She then shouted audibly to her colleague that this customer called her stupid, an obvious lie because all the staff in the store with me could hear both sides of the conversation.
