Proof of Payment Request

I made a claim from my retirement annuities and it turned out that my bank gave me the wrong bank statement and it was transfered into that account. Inorder for my bank to correct the mistake they need a \Proof of Payment\" that will show that the money was coming to me. I made the request on the 29 at butterworth sanlam and was told the proof will be faxed shortly but until today i have not recieved it. I asked the person at the bank to call and check for me and they told him that it will be done by 5th April. This is such an inconvinience for me as im struggling financialy and need to use this money, what taking so long to send a simple peice of paper that confirms that you paid me."
