Sir
I have orderd a bed. I confirm from customer care that it is a double bed..
After delivery on 31st Dec 2019 I canceled the order regarding issue of size..
I got a call and they confirm that sir this is a double bed please don't cancel the order ..I told if it is double bed I have no issue..but again I came to know that this is not double bed..
They told sir it is bigger than single but smaller than double..
There is communication gap between customer and customer service team..
I want double bed please exchange it or refund My money back..
