I went to a branch in Middelburg of capitec and they failed to help me, my account is blocked without me knowing it and they keep on saying that someone sent ***** money into my bank account and of which i dont know who is that person so my question is it fair for a bank to just block my account without my permission as a owner of the accout and they told me that i must go and find out for my self who sent the money of which it was not my fault the bank is allowing ****s into our money and a huge surprise is they say the account is blocked nothing must go out or in but my salary just went in this evening, how is that even possible if i may ask, ayy...no ...no this people are playing games with me and if my money disappear capitec bank will be held accounted
