Pathetic Customer service

My tv started giving problems and I contacted Hisense as it is under warranty last week Monday. I submitted all documentation required and was told all is in order and they will send a technician. After getting the run around and numerous phone calls I finally got them to send someone on the Friday, 4 days later. By Monday I still got no feedback and had to phone multiple times until Tuesday when I was told that they are unable to repair and that I must call Makro, give them a reference number and they will sort out a replacement. I did this and was told that this usually takes 2 to 3 days but they will escalate. Long story short, I received no feedback, no calls whatsoever. I had to use my airtime and call constantly looking for feedback. Then this morning I get told my the repairs dept that I must bring the tv in, they will send it off and I must then wait another week. I inform the lady that everything has already been approved. She tells me that she will get the manager to call me. 3 hours later I call and get told Oh she told the manager and the manager said they will call me at the end of the day?????? I call customer service and no one can even assist me with any feedback. So guess what? I go into another weekend having no clue what is going to happen next......Is this what is called Customer Service? More like treating customers like a joke
