Kenstar — Air cooler service problem

Address: 560087

I have Purchased Kenstar Air cooler Glam 22 R after one week I faced problem in cooling
I contacted customer service center SVC center Apri 21st(Complain No.BAN[protected]) till one week we got no response from either service person or from SVC service center.When we used to call the number no one picked up the number again April 26 we contacted customer care again they told we are not responsible for delay contact nearest service center manager Vinitha:[protected] I called her more than 100 times she never used to pick call.I have never seen such an irresponsible manager in my life she never attended a single call.on 27 service Engineer Dhilip:[protected] came and told there is problem with control board he told today itself i will go to warehouse and bring control board tommorow evening will replace and again no response from any person again we made a call 28 he told control board is not available once available we resolve your problem on May 5 one service engineer called([protected])control board recieved till now he has not yet came when i called him why you are not coming we are waiting for you? He told 'Talk with respect and he is fighting with us.Over all none of these persons in service center seems to be responded properly or never told the truth every time. They used to tell some story.No one in the service center has concern on customer complaints they simply never attend call. Almost all the persons in the service center are in Don't care state only.Till now my problem has not yet been resolved.Is there any single person in kenstar who owns the responsibility to resolve my problem?Over all it is a worst service from Kenstar which i have never experienced such worst customer service from any other consumer electronics company.
