Complain

I have an eGift card first bought online then had a new number to continue using the remaining amount.Went to foschin Nelspruit( Riverside) to redeem the left amount. I was told it says voucher not found, then they called the tfg call centre and they said they will send in 30min, of which I have been waiting for close to an hour before they even called the tfg centre. Decided to call on my own, they said the same thing I must wait for another 30min, I called morethn 4 times but still didn’t get any help of which I waited hours, the shop didn’t even bother calling back to check since I am a customer still waiting to get help. I drove from bushbuckridge to Nelspruit for nothing and Ddnt get any form of help. They recent an email of a new code but still Ddnt work. I waited close to 3 hrs but still Ddnt get wat I drove from bush to Nelspruit for
