No proof but yet case resolved? ABSA deducted R15 000 from my account anauthorsed!!!

Please can somebody explain this to me: I have an issue where ABSA put an stop order of R15 000 on my account. When i complained they emailed me that the case is resolved and they cant do anythong about it? When i asked them if they can provide me with proof that i signed and set up the stop order they told me "unfortunately they dont have that document" I phoned the ABSA branch manager, Sindi to explain to me how they can rule my complain as "resolved" if they cant find the signed stop order and she told me THEY are still busy looking for it? I asked her why they will be still looking for it if the case is "resolved"? Obviously she couldnt answer me. ABSA can you please provide me with my "signed stop order" since youve ruled my case as resolved!!! Its ******* to keep personal documents away from a client and i know for a fact its ******* to put unauthorised stop orders on your clients account!
