I have purchased this microwave oven inverter model. after some months it has a problem. its pcb was short. after leaving the set nearly one month to the service centre it has been delivered to me in an unrepaired condition. again there is a problem with other part . this time the magnatron was damaged. when it was repaired again the pcb was short. this time the warranty period was over. now the company has pushed ball in my pocket and I was told that there is a voltage problem in my home. I told to the company that my other electrical appliances is working well for so many years at the same voltage. I was further told put a voltage stabilizer. I checked the voltage in their service centre it was found same as is in my home i.e. 236 volt. the company is cheating to the custmers in this way
