****med my bank account

I'm writing to lodge complaint about Capitec bank and MTN who didn't refund my money which ****med from my account to another capitec client. Someone made sim swap from my mtn number *** without my consent on the 23 May 2015. My phone wasn't working as from 23 to 25 May 2015 after several times trying to reach MTN call in order to find out what was the problem, then I reach them on the 25 May and told sim swap was made twice under my name. When I went to the bank several transfers were made and airtime purchases to amount of R16 000.00. Worse detective Khubisa whose dealing with case told me that its been two months now after he submitted section 205 but Capitec is not corporating in terms of releasing relevant information to investigate. Instead they are having bad attitude concerning this issue, I strongly believe these syndicates from bank and MTN have succeded with this kind of *****. I only managed to reverse my mtn number on the 14 July 2015 without getting response from MTN which means almost two months with no progress after reported the matter. Capitec bank does not protect their client no even care about them.Please help me to expose and rectify this matter.
