Misconduct and bad customer service

My name is Roeshana Davids I have been a client of Capitec for more than 10 years I have a small home based catering business and was contacted by a client to render a service . for a 60th birthday party in November 2024 . My policy stipulated on my invoice and contract states that 50% deposit is payable on confirmation of booking which the client approved and then made payment after ,the client then tried to reverse the deposit paid to my and reported the payment she made as ***** I had no prior knowledge that she did that until I contacted Capitec to enquire why I had no access to my bank account they then told me the reason without consulting or calling me Capitec blocked my account I then we t to the bank with all requested documents proof of payment the client sent with an advidavate from the police station I was told that it word take 48 hours for the matter to be resolved, I then contacted Capitec the following Monday for an update and was then told it would take 5 business days I was told to resend all the documents again and was give a new case ref number since then theres been no communication i need to call the bank or send an email to get a response the response iv been getting for the past few days is that they would escalate the matter and ask me to send the documents again, the client who made the claim against my account went to the bank and the branch manager told her that my account was involved in *****ulent activity previously and money laundering which I was in total shock and disbelief. I then contacted the branch and spoke to a consultant and was told that the bank had no knowledge of the claim that client said I then asked to speak to the branch manager and he admitted he did say that but he never confirmed he quoted that could be the reason my account is blocked . CAPITEC failed to adhere to the popi act sharing false information of my account to this client. Please advise on a solution my business is running a lost as I'm not able to provide a service and I now need to refund some of my clients.
