Haier India Deep Freezer — Not able to provide to the point service..

Few weeks ago I requested Haier AC service center Azamgarh district Uttar Pradesh for servicing as the AC wasn't working properly. On the first day they told that there is some problem internally and taken the AC with them to service center. After two days they installed it again. Now, there was a new problem arrised in my AC, it started making very much noise. I asked him he said everything is fine it is because of installation. The noise continued, there was another person from LG who cam to install my AC in other room he told that the noise is because they have damaged the wings. When I call to the service center he accepted it. After few days the AC again stopped blowing cool air. I called them for third time he came checked and confirmed that there is a problem with gas, now I asked him to perform necessary action. He again took around three to four hrs installed it back. After few days that's day before yesterday it has stopped working. In the beginning I thought it might be because of stabilizer so I asked electrician to change but the AC is still not functioning. I decided that this time instead of asking again and again to the service center I would directly complain against them. This is getting worst, I Installed AC at home for comfortable living during high degree temperature and I haven't yet had single day without calling the service center.
