Bad service

<p>On the 20 Jul 2016 I logged a request at Mall of Africa standard bank branch, Zacharia Madisha helped log the request. He adviced me I'd get feedback by the 25 Jul 2016. I sent him 2 emails already asking for an update but he doesn't bother responding to my emails. </p> <p> </p> <p>I had a bank account with standard bank few years ago, I closed this account in Dec 2011 or Jan 2012. At the bank branch I was advised that this account now belong to someone, and they're unable to give me any information about the account.</p> <p> </p> <p>I need to prove that this account belonged to me at some point, and that I did close it. Surely the bank should have this kinda information stored somewhere. I was handed over to debt collection a 2 months ago because of insufficient funds on the account in question, I must prove to the debt collectors that they've been trying to collect money from a wrong account but I'm unable to prove this without involving the bank.</p> <p> </p> <p>Can someone please help me? I logged a request with Zacharia on the 20 Jul 2016 already.</p>
