Bad service and terrible communication

The level of communication from capitec is totally ridiculous. My account was blocked and the only communication I got from them was via email and they said it should 72hours....Now 72hours has lapsed they haven't communicated and worse of all they sent a instruction to my other to block my account while they busy with their investigation. I can use my capitec account well but I can't transact on my other bank because of their stupid instruction. They have no respect for their clients or whatsoever. Can they fix so I can close my account with them once and for all.
