UNHAPPY CUSTOMER

I purchased my stove on the 07th March 2014 , It worked fine for 3 months then i noticed there was a crack on 2 plates .Kelvinator technician was called out and changed the plates. I also complained that the plated does not have a constant temperature. The 2nd call out the other 2 plates was changed. Then as time went when i use the oven then i cannot use the plates it cooks very low even if i have it on number 6 temp on the clock. I told Sunnyboy who was now the 2nd technician that this problem is continuing as the plates only last me 3 months then they dont work. He advised Danie his manager to come have a look as he needs to give a report to Robin who can authorize exchanges. Danie also had a look,tested the plates and said he will give it to Robin and he can advise. Now Robin has sent another Technician Tony this is now the 4th guy to attend the same problem.Tony reported now the Grill element is burnt ,cannot understand as i hardly use the oven and the stove not yet a year and he wants to also replace the stove plates for the 2 nd time now.I called Robin to tell him i DO NOT want anything to be changed now as i am fed up and its either he gives me a new stove or a refund.
