Frozen Account Capitec

During the period of July-August 2019 capitec blocked my my account because i received "********** transactions" amounting to plus minus R200 000, these amounts were sales for bitcoins that i owned. When i called or visited the bank i was told to wait for an investigation. After 2 months i got no response so i went to the branch, i was then told to provide proof for source of funds, which i did. But its been almost a 6 months now and the matter hasnt been resolved, with no updates whatsoever. I intend to write to the ombudsman aswell because i feel my money is being blocked without sufficient reasons yet capitec continues to use to their advantage, i had provided all they asked of me, even went to the SAPS but still cannot give me a clear answer as to why the issue is not resolved. Poor Services indeed, They More concerned about their money, customers are always second to their business. They use a small reason to ***** you off your money.
