TFG- R1500 Voucher?

I am very dissatisfied with the service I have received from TFG and it is just very disappointing. I opened a new account a month ago and was very exited about using my "R1500"" voucher. When I opened my account, they split my purchases so that I would received my voucher SMS. After a 2hour struggle, I had no luck and head office could not assist. They advised me that I should received the SMS within the next day. A few days later their customer services centre contacted me, where I also raised the issue that I have not yet received my voucher. She advised me that it will be loaded against my profile. The next week I went to Menlyn. When I was about to pay, I asked about the voucher that should be loaded against my name. After another 1.5hours of waiting, their head office advised that i should go back to mall at reds where i opened my account as they can reverse it against my balance. The next day i went back to Mall at reds where i was told their phones where not working and that i should come back another day. I went back about a week later where i told the staff what i was told regarding the voucher. Again after an hour of waiting, the staff could not even reach the correct division at their head office for assistance. I give them my details as they said that they will sort it out for me. I still haven't hear anything back. I have spend about 5 hours in stores on my feet trying to get this sorted, but still no luck. This is very pathetic! Don't promise something that you are not going to deliver, even after your client has gone through SOOO much effort.
