Hello team

This is to inform you that I purchased a Ac of Havells.
And when it's installed they gave me the bill of ****/-

Even on bill there is no GST number.. ibam attaching the bill. Kindly find the attachment.

Also I don't think so that someone is buying a product of ***** and also paid a installation fees of ****.

Even, the technician is not wear toh company dress...

Kindly solved my problem... Srusly I am not happy with your service.. company is running a scam to steal money for the from the people..also when I receive bill message from the Havells.. it mentions *.**

Technician charged me for wire, stand, even wastage pipe also for installation charge .

Kindly solve as soon as possible, or I will file in consumer court.

I am attaching all screenshots.

Thanks and regards
