Address:	500016
Website:	Blue star ac

Purchased a blue star split ac on 26 may 2017, from adith electronics ameer per. 27 th may technician reports for installation with inadequate tools. Blower shows er6 code after installation, which is rectified by installation guy saying some sensor was not connected. Right from day of installation outdoor unit making lot of noise and vibration. We were unable to sleep for 2 nights. On inspection found that the outdoor unit was not fixed properly to the frame. Raised a complaint again, another guy reports and again has no tools to tighten the bolts. Complaint is closed without rectification. Agaim raised complaint on 6th june2017, service promised within 4 hr but no response from bluestar. 7th june 2017, agaian called up bluestar with complaint ts of noise and vibration at 11 pm. 4 am ac stopped working.
Is there any existing customer care service existing with bluestar.? What is the quality of these air-conditioners sold. Hope my problem is solved and agony of disturbed sleep too.
