Disgusted TFG Vouchers no service

I recently bought a new home and opened the TFG account as I need some home essentials. It was advertised that I could get the vouchers so this was very appealing as I was trying to save money as well as get those essentials.

Activated the new account at Blye Route Mall. 3 weeks later mo vouchers. The best part was I got a call from client services to rate service and I mentioned the vouchers. I thought that he would take it further. At this stage quite frustrated I emailed a few times. Eventually the vouchers were sent which expired 12 July. The vouchers were send after I purchased a pair of sneakers which were pricy i could not use the vouchers on the Nike Air Force. I was once again disappointed. I went to Cavendish at home on the 8 July. Produced the voucher code the teller said the vouchers have expired. She did not bother to call in and that was that. I am quite disgusted at the purchases made could not use the vouchers and staff who no not go the extra mile. I would close this account today if I could and open one where there is readily customers service. Do not send a link to a survey after each visit because it fruitless. I would like a response back from management and would like to apply my vouchers to every purchased ALREADY MADE. I am appalled at the lack of concern shown to these vouchers and how seriously TFG treats their customers
