Godrej — Defective and expensive product

Dear sirs,
The odu supplied to me along with the idu against the
Invoice no: 10007di11151605 dtd:[protected] is delivered to me with out filling the refrigerant ie fluride r32.
After using for a week i found the defect and become mad of the issue because i have spent a big amount.
I have lodged a complaint also on the same at your head office.
So i request you to kindly replace the useless odu with a power odu with the refrigerant duly filled at your works and deliver it to me at the earliest.

Thanking you
Rkp hyd
