Deposit payment not reflecting

<p>Morning, Please help I made a payment of R510,00 at ABSA ATM for MTN mobile in October 2016, I lost the receipt now MTN took the account to their Legal departmet. I fail to understand why, they said they cannot trace the payment but I used everything they said I must use. If the reference number is ok why can't they find the payment. I feel betrayed as R500 is a lot of money that I don't have. I went to Mimosa in Bloemfontein many times but I always get the same answer. I wrote to Legal Department, they also want the proof of payment which I do not have. Is it that difficult to trace the payment with the reference number? I finished paying for the account now I have to pay for Legal Department as well. Please HELP me.</p>
