I had purchased vise brand air conditioner from Vijay Sales.
At that time they had told about free installation. But when their technician came for installation, he quoted double the market rate for extra copper pipe, electricity wire and stand of the outdoor unit.
They were looting in the name of free installation.
The copper pipe was supposed to be 6 feet only but he was telling me it was 8 feet.
I did not get the installation done by him, I got the installation done by some other technician from outside and he did the installation at a very low rate.
