Capitec just froze my account for selling my salon equipment

I hereby request clarity on a matter that needs serious attention.i sold my office equipment on market place money was deposited and I received a notification,later on I tried to transact I couldnt .I printed my balance it appears.called the bank to enquire about such situation I was just told plainly that my account was involved with ***** and the consultant dropped the phone.i then contacted my attorney to try and seek anyway forward as I didn't receive any communication and whatsoever as my goods were long time delivered to the buyers. After seeking my legal advice I was then told to contact the bank or visit the nearest bank and seek answers from and qualified investigation officer The further highlight the obligation of FICA and the evidence that they have collected in order to take such a hush decision to freeze my acc if I am not contacted shortly I will have to file a dispute under regulations 7(Ii) of financial law as the bank won't replace my lost goods according to your disclaimer that you are not legible to pay any money but without proper investigation and communication my account was froozen for 3days
