Godrej Interio — Sofa cum bed

Address:

hyderabad

I have purchased a sofa-cum bed in august 2018. The backrest has two knobs on the either side. One of the knob as come out. I have lodged a complain in customer care. The technician (Hyderabad) visited and said though he has never seen this product, we will take it to the workshop and get it done by third party.

The owner of the service centre mr darius phone no, [protected] called up and said that including transportation (Hardly any distance) and the welding it will cost around rs 12302/- (Including gst). The breakup is also not mentioned. I have attached a copy. Is it a joke?
He was very rude and said though we do not do sofa repairs we are obliging. Then the question is when godrej does not have service centre for sofa, why do they take the complain? Technician has taken rs 400 visiting charges for what?

Please take it on priority.
My house entire interiors is from godrej. Now i doubt that in future if i have any issue with any of my product, what will i do?
