BAD CUSTOMER SERVICE

I have a problem with the bad customer service that I am receiving at Lewis store in Randburg and their Head Office. I reported a matter in store in May 2020 regarding the fridge I bought that it is not working properly but they gave me a lame reply. Now the fridge is not working completely I lodged a complain in their Head office on the 1st of December 2020 they have been sending me pillar to post i am the one who has to call and ask for updates of when is the technician coming to check the fridge. The technician came and told me that he can't do anything with the fridge it must be sent back to the warehouse and the store must give me a fridge to use in the meanime, they came after I again called their head office and the store asking them when are they coming to collect this fridge. They came and collected and left me without a fridge. I am sick and tired of their nonsense now. When I call and ask them what is going on they tell me that the person that is suppose to call me is busy she will call me later since last week Friday. I am wasting money buying food that gets spoiled and I throw it away but I am paying them and I have never skipped my installment and also paying for insurance this is nonsense really spending my festive without a fridge. And now I don't want that fridge that they are fixing I won't pay for second hand I want a new fridge. I cannot be treated like this as if I am not paying. Even today I had to call and ask and I am tired now I have had enough wasting my time and my money calling them as if I'm begging.
