Bank account stopped without communication

I'm very disappointed with Capitec Bank. I've been banking with Capitec for twenty years, yesterday I found out my account in frozen by some Cape Town court due to maintaining case Idid not attend. Capitec bank did not see the need to inform me I only realize this while purchasing groceries and the card keep declining. As a client I expected to notified,when I asked them for more info about so-called court documents they are unable to provide. So that means anyone can decide on my money while I'm still banking with them. As soon as issue is resolve I'm changing banks.
