Waiting for a technician for more than 10 month!

We bought two Defy stoves on 08 Oct 2014 . We had it installed by an electrician and found both to be faulty !The one is down to earth on one of the stove plates while on the other one, all the other three plates and the top of the stove become untouchable hot when one stove plate is switched on. On this stove the oven door is also faulty. The customer service said they will send a technician to check if they are repairable or not. The technician came and could fixed the earth connection.But for the other one he said they are out of spare part and he will come back as soon as they receive the parts. After ten month, I a, still waiting for the technician to come back with spare part. No one is responsible about this poor quality products, poor quality of service and poor quality of customer care. We are extremely dis-satisfied with this bad quality product. It was bought in good faith as we reckoned that by buying Defy from Metro, we are buying a good brand at a well reputed outlet.<br> The Invoice Number is ***3.
