Capitec is allowing a ********* mess with my life and they are doing nothing

Capitec bank is supposed to protect my money but instead the bank has chosen to let a ********* put my life on hold, I discovered my account was frozen on 19th July and upon contacting the bank I found out that somebody who had made a payment (as payment of an item sold to that individual)to me a day before had reported the same transaction as **********, 20th I was at the bank providing evidence of sales,receipts and even proof of payment sent directly from the bank to me when the payment was made,I also provided records of my communication with this person who swore that she didn't report the transaction. Thinking with all evidence provided Capitec will be able to do their investigation on time and release my account and funds, my biggest surprise is Capitec still asked me for the same evidence today 25th meaning nothing had been done within a week of providing all proof required. Capitec was fast to freeze my account without proper investigation and now that they have evidence of my innocence they are reluctant to do their job. The money in question was immediately removed from my account by Capitec but the rest of my hard earned money is still being held by Capitec and they are refusing to do their job.
