TERRIBLE SERVICE FROM TELJOY

I have been a client with teljoy for just over 3 years and have rented 3 appliances from them. In middle dec there was a thunder storm and lightning struck out my tv. I have reported the issue to them and after n long wait they eventually came to collect the tv for repair. After a while of hearing nothing, I had to phone to follow up, and they informed me they are waiting for a part, but will send me a loan unit in the mean time. Again I heard nothing and I had to phone them for an update. After that, they told me the tv is not repairable and they are going to replace it. Again nothing happened as they were "out of stock", and I phoned them every day to follow up and everyday I was promised to get my new tv tonorrowand tomorrow came and nothing happened.... eventually they phoned me and said they dont have my tv in stock but they will send me a better model as that is what they have in stock and I accepted. After almost 2 weeks.... nothing. So today a man came to deliver my tv.... he never gave me a remote..... I tried figuring it out without the remote and saw it was scratched on the side... I realised that the tv was never in a box or sealed with the plastic a new tv is usually covered in!! They gave me a 2nd hand tv without a remote??? After spending hours of MY own airtime everyday.... I have only received empty promises from these pweople.....What do I do now?? I am going to stop payment and I will put up this TERRIBLE SERVICE review on every social media platform I can find!!!
