TFG cust services, payment arrangements email service non existant

I paid R2000 on the 1st of Sep into the wrong Foschini acc via EFT. When I started getting messages I realised the problem and immediately printed proof and sent it to TFG. Since then I've sent 4 emails with proof to kindly request them to journal it to the correct acc. No acknowledgement of my mails, in fact it has been given over to legal. Worst of all the payment was nearly a double installment and its in their bank acc, all they need to do is assign the payment to the correct acc. Yes I made an error and I immediately tried to rectify it
