Poor/Bad customer service.

I purchased a 65" Samung Smart TV from Makro Cornubia last year. This past Sunday, the TV stopped working and I called the Makrocare Contact Centre ***) on Moday and they emailed me with a request number (***) and they requested various information (details of TV, markro card number etc). I responded immediately with the details. I called through on Tuesday to follow up and was advised that my request will be captured and that I must follow up after a day. I called through today and advised that the request was not captured as my makro card details is incorrect. I provided them with the updated details and they now confirm that the request has been logged and that I need to wait 5 business days before a service agent comes out to check my TV. This is very unprofessional and bad service as I called through two days ago and only now my request has been captured. Also , no one is calling me or emailing me to provide an update and I must waste my airtime to follow up with the request. It is now three days that I don't have a functioning TV and now I must wait another 5 business days for someone to assist me. I desperately need urgent assistance...
