Reverse my money

I have a loan with you guys and have been trying to make an arrangement with you guys to the extent that I went to the branch with all the documents as I have lost my job,was then advised to call back once I receive the uif funds,but you took everything as soon as the money went in even before I could call in and when I called the collections department I was advised to complain..was told by the agent (glitter) that the manager is refusing my escalation. Your business policies are selfish,your staff has the poorest of service I regret the day I took any services from Capitec bank. You keep saying I had no arrangement,yet you took 3 installments at the same time... Who gave you the right to do so on my account???
