company won't clear my payment

I made a payment of 1700 on Friday 27/03/2015 via cellphone banking and I called their call centre to find out what's the next step. I was told to fax my transactional list showing the payment. I did that (online banking transactional list), sent them the text message and after two days Nonkosinathi Nongwe rep**** with this: Thank you for your email. Please send us a copy of your transaction list from your bank to assist you further. I sent my transactional list and I circled the transaction. Two days later the same person rep**** with this: As previously stated that we need a proof of transaction list from your bank stamped by your bank for further assistance.<br> My problem is the payment I have made can be easily traced with the information I have provided Capfin. I don't get why this nongwe person didn't tell me I should get a transactional list with a bank stamp. I have a 9-5 and don't have time to go to the bank. Its been more than a week and this person who is replying to me seems like he/she doesn't care, they take forever to reply and are not specific. Can the company just trace the payment and credit it to my name. I am really annoyed. They continue debiting my money.
