Blue Star India — split a/c, 6th september

Address:

560094

I am one of your customer using blue star split a/c. I called your customer care number to help me with annual maintenance on 6th of september. After that i received a call from
1. [protected] it said dialto repair - home appliance repair and service they booked my service and said technician will call me. This was at 7.57 am
2. Then i got a call from [protected] asking for my address and i sms this person my address.
3. One person comes to my house, doesn't know what he is doing. He is constantly checking with someone on what to do and finally said he has filled the gas and did servicing and gave a bill. He charges rs 2800/- for filling gas which was almost rs 1000/- more that what i have usually paid.
4. As soon as he left when we tried to switch on the a/c, it started making noise and it would not cool. Next day i saw full ice being formed on the tubes and a/c was not working. When i called the person, he said he doesn't know any thing and asked to call main number and book complaint again.
5. When i called dialto repair the number keeps ringing with no response. When i call cell number [protected], a lady by name alia took the call, she said she will investigate and come back, she has not done so far.
7. If i try to call number on the receipt it comes switched off.
I feel this is a fraud company taking customer numbers from blue start service number and conning them of their money.
I need complete investigation and refund of my money.
Subsequently i called another service center of blue star and they came and repaired the a/c and charged be again rs 3550/-.
