Blue Star India — ac installation

Address: 500049

I have raised request for installation for new Blue star AC. Passed three days till now no one has given a call on this. I have called 6 times to custermer care, they simply says we have escalated the request. As of now no response... Instllation people will never pick the phone i have tried more than 20 times. No use. For my view my first impression was gone. Going further i never ever prefer Blue Star. Technician name as "ESA Gayathri Cool World" [protected]
