****med out if my money

I made a payment on the 7th June 2019 at a FNB ATM for my mom with the details sms'ed to me. Up until now the payment is still not allocated and I'm still receiving harassing calls from Foschini threatening with final demands. I called the call center last week and spoke to a lady and advised her of what is happening and she advised she will call me back and still still I have not received an call back from Foschini. I called again today and spoke to Lwando and he advised that they had an issue with payments made at FNB whereby they were not reflecting on customer's accounts and asked that I send a proof of payment and I advised him that I no longer have the proof of payment because I assumed when I deposit money into Foschini's FNB account using the correct reference number, it should reflect automatically. When I told him that i no longer have the proof of payment, he told me they will nit be able to help me in allocating my payment into my account. I asked to speak to his manager and then a lady came and spoke to me who also advised the same thing that Lwando had previously said to me before escalating to speak to a manager and she was very rude and sarcastic because when I told the lady it's not my fault that the payment is not reflecting, she responded by saying it's not their fault either. I escalated further and asked to speak to her manager and she did not place me on hold, I could hear speaking in the background and laughing. I then spoke to her manager who also sounded very irritated and annoyed to assist me. She did not go the extra mile in assisting, all she did was just give the remittance department's number to call instead of answering the questions I was asking about the payment that I made.
