voltas company misleading customer

Respected sir,
It is to inform u that I had a complain regarding stabliser and AC against voltas service centre on 11th of may 2014. His technician came and collect it on 15th of may 2014. But till today I do not get back my stablise and ACr. I called them on daily basis bt they are not taking any proper response. They assure their service within 24hrs. But here 2 months is goin to pass now. Almost summer ig goin to be over. I am facing so much problem. I am renting a stabliser from 11th of may and they are charging for it. Now its a duty of voltas to compensate the rent. Full compensation is 10000. My registered mobile number in voltas is 9560476735. Please help me out as I am facing lots of problem and take proper action against Voltas. Thanking you.
