Bad customer experience at Lewis Denly Mamelody Pretoria Gauteng

I purchased a fridge from Lewis Stores Denlyn Mamelodi paid my deposit fridge delivered. In my first month of payment I had an experience out of my control where i had to close my current bank account and had to open a new bank account but at the same bank, I could not make payment contacted head office and the adviced i should contact the branch and advise, which i did The branch blatandly advise i must pay even if i had to borrow money or they going to reposes the fridge, ive asked them to give me time or until month end to come and pay which they refused and repossesed the fridge. ive forwarded my new banking details for them to reload a debit order and received a sms from the stores to say i have a new account, When i went to pay my first installment month end i was told the account is closed without notifying me and i lose my deposit becaue i used the fridge. I advised them but im coming to make payment and they can go ahead with the debit on my new account number they just shrugged up their shoulders saying there is nothing they can do. I feel this is extremely unfair handling of a customer espechilly since i paid my deposit and experience a concern out of my control. Ive tried to contact them numerous of times but the sales person rudely advised he cannot share managers contact details and nothing can be done, I would like my deposit back please or my the fridge as i feel a customer should be given a fair chanse in the matter. Please advise with urgency. Please note i have also sent two complaints to your head office without acknowleding receipt of email or any replies to my complaints. your swift response will be highly appreciated please. Thank you
