Saravana Stores — revolving chair

The chair was delivered yesterday
While unloading from the truck the wheel part fell down with severe impact on the road.
The delivery boy came and kept on the hall when asked why did it fall off he just smiled
Then he pressed the seating cushion with his knee and told it's ok
Is it the way the chair has to be delivered why undue care is not taken while handling these things totally upset don't know when will this will break .
Totally unprofessional approach.
PL provide me a solution/compensation for this
