I want my instalments amounts.

I cursed the day I went to their dealership since March I have been fighting with We buy cars to make me happy as the client and they keep failing me now we sitting with a new problem where they are failing to refund me my money I paid for the car after they have promised to pay me back my instalments I have provided them with all relevant documents but still I'm not getting my money, thanks to the lady who have been trying by all means to help me from day one her name is Kimberly I will definitely adv anyone having problem with this nonsense company should ask her for assistance she listenes to clients and try her best to help but where she sends request they're failing her. I want my instalments back I never gave you guys problem when you asked for the usage amount.
