defy is taking me for granted

I bought a fridge and the rubber on top was coming off on top. I went store they did pick up and exchange. The new fridge gave me same problem. I called defy and spoke to Mark. He said to me he will send a technician and get back to me, it was friday. On tuesday technician called me and said his car have a problem. We rescheduled for Thursday before 12 which he came after 12. Technician said told me that my floor is not level that is why the rubber come off. I'm not a technician but I'm not an idiot. I wonder if he was there to fix fridge or floor. After the technician came I wanted for Mark's call. He didn't call, I called him back only to find out he didn't bother to make a follow up. Now he is telling me he have to send a technician again for same problem. If I the technician couldn't do the job first how will he do it this time? If Mark didn't do the follow up and get back to me what will change this time? If I didn't get back to him when was he gonna send technician again? The fridge is costing me electricity since is not closing properly. The fridge is not even a month old. Mark and his technician played me a fool. I want my money back time to fix has passed now.
