Great Eastern Trading — Poor service & defective ac machine

Address:	North 24 Parganas, West Bengal, 743127
Website:	www.greateastern.in

On 11.06.17 i had purchased lg lsa/lsu 5sp5d 1.5 ton split ac 5s i/o
During the purchased great eastern trading barrackpore offered me free installation & bracket angle free along with ac machine.
On 12.06.17 the machine was delivered to my address.
On 13th i got a call from the ac installer who wants to visit for installation on 14th but i requested him to come on 17th saturday for my convenience.
On 17th when the ac installer came to visit they informed me that installation is not free they will charge 1750/-
I called barrackpore great eastern immediately & surprisingly came to know that they had wrongly informed to some other agency instead of sn agency who will install the machine in my home for free of cost.
I requested them to inform the sn agency so that they can visit on the same day & install the ac.
On the same day in the evening ac installer from sn agency came & informed me that they won't require any installation charges as the installation in free for my case.
The installer started doing the initial activity when we came to know that manual, ac remote & other necessary wires were not available in the carton.
Immediately i called barrackpore great eastern initially they denied but since the carton was opened by the ac installer barrackpore great eastern had to admit it.
I requested them if they can send someone to my residence with the materials so that the ac installer can do the needful.
Barrackpore great eastern refused to send someone instead they asked me to take the delivery from the branch, accordingly i had visited the branch on 17th evening & took the delivery of remote, manual & wires, on asking they simply replied it is not their fault the company has forgot to send this things in the carton.
I had requested them to send the ac installer next day so that they can install the machine, they confirmed me that sunday morning ac installer will visit to my residence.
Unfortunately till 3pm i didn’t have any clue if the ac installer will come or not i had called at least 10 times to barrackpore great eastern.
Finally at 6pm in the evening ac installer came to install the machine by the time they have done the ground work it was already dark, the installer carry on the work with the help of torch light.
At 7.30 they finished the installation & turned the ac surprisingly my indoor was not working then on searching the reason the ac installer told me that in the outdoor machine fan blades are not moving as the blade size is bigger that the space, more over they start talking within themselves that earlier there was some maintenance work happened in the outdoor machine.
When i asked the installer they denied the fact & assured me that machine is fine only thing is they need to cut all the fan blades half inch o that it start rotate.
Immediately i called barrackpore great eastern they told me they have nothing to do with it this is the common manufacturing defect & found in multiple cases.
Once i didn’t get any assurance from barrackpore great eastern i had to go by the cutting option of fan blades, accordingly the ac installer tart cutting the fan blades & finished the installation at 8.30 pm, entire outdoor fitting was done in torch light.
I am afraid of my ac machine really i don’t know what to do should i run it or not as now the blade sizes had also becomes small, i am afraid if the small blades can perform well or not.
I am also surprised by the approach of barrackpore great eastern staffs the way they had dealt with the entire lapses.
At the same time i am shocked how a company like lg can be so irresponsible that they forget to provide the necessary materials in the cartoon & most importantly how they send the defective piece in the market.
Please help me to overcome the situation & guide me.
