Panasonic — Air Conditioners Installed by unprofessional team of Panasonic Service Center

I have purchased Two Sanyo Inverter Ac 2 ton and One Panasonic Inverter AC 1.5 ton and Installation done by Panasonic authorize service center, The installation was really very poor, the Installation persons are unprofessional and uncooperative, seems they are taking installation training and doing trials at customers ends. I told them to get it installed by professional but they told we have enough knowledge, at last unexpected thing happens which I am worried for, the interconnecting copper pipe is not bend properly in shape and cooling is not coming in Sanyo 2 ton inverter Ac, when I forced them to check than they remove the form from copper pipe, the pipe is totally bend and damaged. I really got disappointed and annoyed on purchasing Panasonic Manufactured Sanyo branded AC and get it installed by brand service center, thinking in mind that it should be best installation by brand service center. But the installation was really very poor by unprofessional team.
After that they cut the interconnecting copper pipe from between, remove the bend portion and reconnect it by doing welding without removing indoor unit. The side thermacal and plastic body of indoor unit was also get affected by heat while doing welding on copper pipe and they left cover open after doing wiring of outdoor unit.
At time of installation of Panasonic 1.5 ton Ac the installation person doesn't remove the corrugated cover which was inserted on back of outdoor unit to prevent fins in transit, such a careless staff by Panasonic authorize service center, they doesn't remove it and ac is running but it's not cooling due to it and outdoor unit is overheating.
Really very very bad experience and disappointed after getting installed by brand service center, they are unprofessional and untrustworthy staff, it's better to get it installed by local installation person whom we know.
Hope you take strict action against service center of Karnal

Hope you take this matter seriously otherwise people will loose there trust on Panasonic brand if you will not get your service improved. so please hire professionals for installation.
Customer trust the brand and pay hard earned money for the product but due to poor service by authorize service center will make customer think twice to purchase any product again, So you should provide good service from authorise service center or change service center in our location to make brand goodwill, the Panasonic center of Karnal is really giving very poor service by unprofessional team. Now I am worried for recently purchased 3 AC, should I get good service in future or not.
Hope it will get improved and strick action against present authorize service center of Karnal.
Thanks
