Pathetic service, planning to sue if possible.

So the shiit heads at Capitec decided to block my account 2 weeks ago without even bothering to notify me about what they've done. Last week Thursday I recieved my paycheck so it seemed as if all was well and good.. However, to my embarrassment, I get hit with the "insufficient funds" notification when I try withdrawing cash a day later.. I go check my app, my literal account information is simply not there... I go to the nearest branch to find out what happened and an agent there tells me the account was blocked... Along with that, of course they couldn't tell me why it was blocked either.. I had to wait an hour or two to do a follow up on their useless WhatsApp platform, only to be told by SMS soon after that there was a *****ulent transaction in my account 9 months ago, for a figure of R20, that someone else sent to me. I followed all instructions and went to a policy station to get affidavits made and what not, by 10:30 Saturday morning those documents were submitted to the branch.. It is now over 48 hours later, I have missed every single one of my 7 to 10 debit orders that were due on Saturday, along with my rent that was due in the same day.. So what do I get told today when I wasted more resources and called them, "the event is being investigated" and that's the only update they can provide.. Whrn I came on here to log this complaint, I came to see the fact that atleast 3 other people are dealing with the same issue as we speak.. This useless bank is literally *****ing our funds for who knows what reason right now, and probably soon after this, our account will be unblocked with no real explanation... Who can advice on how this matter needs to be dealt with because I have all intention of suing them if possible based off this experience...
