E-Gift Voucer

This is my last resort...!

On the 31st March 2021, my Mom made an e-voucher to me for the amount of r1.100 which we normally use without any hassles whatsoever. Fast Forward to the 3rd April 2021 I go to SodaBloc at Mimosa mall to buy and the Voucher does not go through and the lady assisting me there says I must just go to any other TFG store to try and use it. Then I go to Totalsports still at Mimosa Mall and still voucher does not go through, I then ask Mom to go ask at Exact Store in Thaba Nchu where she made the Voucher as to what could be the problem, the gentleman at Exact Thaba Nchu then calls me to ask as to what's happening, i then tell him as to what the problem is and he asks that i go to any TFG store on Sunday and try, it could be an error or maybe the systems were just offline and then on Sunday the 4th April I go to Totalsports at Twin city Mall in Heidedal, the assistant there then calls the customer service which they tell her that the system is being upgraded and it should be okay during the week. Well, since I knock off late, the only time I manage to go to the stores is on weekends and on the 11th April I went to Exact Loch Logan and it still said INVALID Token, I then leave the store with much frustration of this e-voucher and I decide to go to exact where this Voucher was made(Thaba Nchu) , the Lady(Portia) who has been soo much patient and helpful to me calls and tries to find out what's the problem. The voucher was rectified however now the remaining balance is r776 and no longer r1.100 and she calls again to find out what happend to the r324. Apparently the Voucher bought on the 3rd April at their store in Thaba Nchu while the SMS was with me all this time and I was in Bloemfontein while all this happened and no one seems to be of help to her because I go to the store almost everyday and we reach a dead end. Having said all of this, there's no record of this transaction at the store. They printed out all the 3rd April Receipts and EFT and it does not appear anywhere.

Kindly assist on the matter, as no one can account for the amount. I did send an email to the online@tfg account and it seems my cry fell on deaf ears.
