Device sold

My name is Sylvannah Morgan. I went to do loan against my phone at cash crusaders Springs? They do give you time for extensions. During my extension time they sold my phone and also put my other item on the floor to be sold. When I enquired about paying the interest I was called to the store. Upon arrival I was told they had made a mistake and sold my phone and while in the store I found my Xbox on the floor to. They were about to sell it yet I had asked to pay interest. I then had another item a television which I also made a loan against. I received no notification as when my contract lapsed though I had been communicating with regarding my phone. To date I haven't received any feedback, they haven't replaced my item and now they expect !e to sign a contract agreeing to accepting a second hand device and repaying my loan. I'm not satisfied as my cellphone is only a year old and was in perfect working condition. I as the customer needs should come first. I feel agrieved because besides the device I have lost information, memories,pictures and alot for sentimental things then the phone. I believe my device should. Be replaced by a new device or the device price should be checked , they take their loan amount and pay me the difference cause currently the store will benefit on both sides. !y device is sold, they finding a second hand device and I'm expected to repay the loan amount and then accept a second hand device. I've reported the matter to head office it's been 2 weeks with no response or feedback. Can I kindly get assistance in this regard
