Blocked account

Greetings, I'm more than desappointed with Capitec, they blocked my account without any reason and they are insisting that they won't open it, with my policy I can give them another account for them to deduct the monthly payment. My question is if something can happen how I'm going to claim it because as now they can't able to see if is updated or not. Capitec just made my life deficult from the 9th of September till today, as I speak I couldn't pay school fees for my grandchild and transport I'm struggling with the 3 kids no food but I know that in my Capitec account I have R2200 that I can't access it its really painful the way Capitec treat people. I wish they could give me my money then close their account not to let me suffer like this with kids
