Blocked account

I had the most terrible experience with Capitec. A few days ago I was traveling home to a different province and I stopped to fill up fuel. My card declined and when I checked my account balance, it was empty. I called the bank and they told me my account was blocked. I could not believe it as I needed to pay for fuel and I’m already on the road home. I was told I need to make an affidavit to explain my side of the story to have my account unblocked. It seemed I was being treated as a ******** that must be investigated. They said my account was linked to a series off ********** account numbers and has monies coming and out. I have investments and business I run and of course, monies will come in and out. I’ve sent the affidavit two days ago and up to now my account is still blocked. I am in need of my money and Capitec is keeping it. Unfortunately my kids cannot go back to school as I am financially disabled. I can’t express the pain they ar putting me through for my own money. Hopefully some day they will think to come to my aid and give back my money.
