[Resolved]  Samsung Window A / C 1 Ton & 1. 5 Ton — Exorbitant electric bills

I am from mumbai, tardeo purchased two windows a/c [i think biggest mistake of my life] of 1.5 ton & 1 ton from Kohinoor Electronics, Dadar in exchange of LG window a/c. The complains are as follows
1. My a/c was never serviced by the company on its own. Unless u call them. they are least bothered. [LG on the other hand gave atleast my all services of the warranty peroid on time without me callinf them.]
2. LG was around Rs.1500 cheaper than Samsung the day when i purchased the product but it made me think that may be the higher price is better quatlity but it is a a/c.
3. On callling the service center for servicing the person comes after two days. that too before coming he calls that is expected to come in 2 hours. But the bloody chut does not turn up nor had courtesy to call. The next day he comes like a fool without a blower and says we service the a/c with a toothbrush only and a bowl of water.
4. Till i had LG our usage was around 10 to 12 hours daily and our bill was around Rs.4000 appprx per month but the moment i changed to Samsung the bill has continuely increasing. Today the bill has come is Rs.12000 per month which is bloody shocking.
I made a complain with BEST they came and checked the meter which is perfect.
I strongly fell the bloody a/c is only faulty.
5. I donont know what to do can u please help me for the same.
6. My complain number is [protected] made on the help line number 30308282.
7. I am sorry to use foul language as i so fed up with the product that i really donot know what to do The A/c is just 12 months old and i exchange the a/c with new one what is get is just Rs.2000.
