Capitec Bank debit order

I am disappointed with the processes that Capitec has for their loans that are in arrears. They do not take the client's financial situation into account. I lost my job and made arrangements with capitec. I was told that the arrangement was for me to pay a set amount monthly. To my surprise they reverted to the initial instalment a month later. So I decided it was OK they could do that because that was the initial installment I had began with. 59 day after that I get a deduction of the arranged instalment. What the heck so I go to their branch and get told that it can be reversed and that there are arrangements in place going forward. A month later I get debited two instalments of the original installment. In a space of 2 days. Guys what is going on. When I get to the branch I'm told it can't be reversed because I don't have an arrangement. I know I owe Capitec but there is no company that will deduct twice in a week for a person who gets paid monthly. Please return my money

And how can a branch not have a phone number for its own complaints department. Really now.
