Frozen Account

On the 04th of October 2019 I received a payment from a client on my Capitec account and the following day 05th October my account was frozen without notice, I went to my branch for enquiry on the matter and I was told it was due to claimed ***** activity that was reported by FNB. The money was transferred from an FNB account.I've been going back and forth to the branch and they telling me that the is nothing they can do my account will only be unfrozen when the complaint say so and the painful part is that they frozen the whole account even without getting my side of the story and now no one is willing to take interest in helping me sort this out. Am disappointed in Capitec bank. Please respond urgently to get this matter resolved before I consider further action
