TFG eVouchers

I am so dissappointed at TFG group as a whole. I received a voucher via sms and I went to Foschini Trade Route Mall to redeem it. They told me the voucher number was invalid. I called the customer service the next day as they refused to contact the customer service saying they don't answer call on weekends. The customer services confirmed the number was correct and I should go to store and ask them to call customer service if they are not sure. So I decided to go to Total Sports to redeem there, the guy who assisted me when to enquire with the manager and came back saying the voucher can only be used at Foschini as it was received from Ponds Company. And he was adamant that the information he got from his manager was correct. I again called customer service and the lady by the name of Thembi confirmed what the store told me. She said whatever the store told you, is correct....I called again to confirm with a different person as the vouched stated that it is a TFG voucher. The person i called said there is no such thing, I should take the voucher to store and let them call the customer service. I went back to Total Sport Lenasia. They told me that they are not sure what to do and when I asked them to call customer service they told me they have problems with their phones. I had to use my phone again. The person who answered the call told me that the voucher is to be used at Jet Store since I have an account there, I told her that she was wrong because I was told I can redeem the voucher at any TFG stores except Jet. She then said "Oh, sorry". And she asked the sales consultant to email the voucher to them. The voucher was emailed and I waited hours for them to respond. Eventually, the sales assistant was told to select e-voucher on the system when redeeming the voucher. I mean after so many days going back and forth to stores, hours waiting at store. This is what they needed to do.....And the sales consultant expected me to buy her lunch/drink after she spent so much time on the phone to get the issue resolved......I have never seen such a thing in my life. I would suggest you give proper training to your employees at stores and customer service about such things. It is really disappointing, time consuming and annoying to deal with things like this.
