Carrier India — Defective products

I had purchased an carrier company split ac, from godavarikhani, dist: karimnagar, telangana state. Sai krupa electronics, on[protected]. I had request an complaint for installation of ac on[protected] on req no: 91393740. On[protected] companies technician visited my place and installed that ac, but soon after installation ac was found defective as it was not working properly. On asking technician said it could be minor fault or else any transportation damage, so if any part is broken they will change the part. When we asked about this to company even they refused to replace the new ac as they said only for any part they will not change the complete ac. After long discussion i agreed for replacement of part instead of replacement for new ac. But till now there is no response from company. After calling company again and again they send one of their technician for replacement of part in that ac, but he found that is was not the part damaged but something internal and major genuine problem in ac indoor. He said he will again change that part also and went back and reported in company that part is replaced and problem is solved. After an week i. E on 10-06-15 i called company regarding this ac issue, i was shocked to hear the report submitted by the technician, when asked to the technician person he said that it could be by mistake they taken that report. This was the height of patience. When i called companys customer care and asked them how could they do like this, they are just trying to skip out of this matter. I am fed up by calling this company person daily for this issue, but their is no response from company. Kindly take some serious action towards this company and solve my problem.
