Teljoy bad bad

Bad bad bad. Will never ever recommend that anybody buy anything from them. Ive bought a few appliances on rental. Last year nov they forgot to do a re instatement of the debit order. Didnt notify me if anything beginning of jan i started getting mails and messages that im in arrears. Portia called me feom collections and told me how sorry sge is for not doing it and didnt notify me. Got the proof of the conversatiosn aswell. From there no one want to assist me. Dont call me back etc not replying on my mails etc . My one appliance contract did expired the 01/01/2022. Last year ive sent a mail to let them know im taking ownership of it. Ive even talked to acc and Portia. But still they deducting the money from it. They dont want to talk to me or reply on my emails etc. Now they just keep on deducting. If i stop the debit order they will threaten me by taking back my applainces It has already been handed over to collections. So what must i do???
