Wockhardt.com — glaritus dispopen

Address: E-33, Bali nagar, New Delhi, Delhi, 110015

I ordered a glaritus dispopen through 1mg app.. I open the dispopen and after putting the needle.. Find the top cap is loose.. It is a manufacturing defect which one can only identify when one uses it.
I complain to 1 mg and they say. It is not our fault, you should have checked on delivery..
Even if i open it.. I can't find the defect.. Till i use it.. Now i am stuck with it..

It is a manufacturing defect. So ideally wockhardt should take responsibility.
