Disgusting Services from Capitec

Capitec is one of the worst banks ever! they have put my funds on hold due to their investigations, fine I had to make other means to make other ways of making money, so I sold my car to Gobid, now today they also put the funds on hold, for what reason I don't know, seems like they don't understand how serious these kind of Issues are... I have been waiting to go home for a funeral. How do we deal with banks who does this to its client.
