OnePlus India — oneplus 5 mic issue

Address:	560025
Website:	oneplus

On[protected], i bought a oneplus 5 mobile (A5000_in_64g_slate grey) from amazon.

Unfortunately from 2nd month till now your product has not performed well because (I am not able to call any person as there is disturbance while calling, in fact i clearly explained this to engineer several times about the problem). They ended up just flashing the mobile or factory resetting it stating that might be a software issue each time i visited the care center.

I am disappointed because after visiting service center multiple times may be 7-8 times the product does not seem to be working properly.
The work done on the mobile was half-assed and i am pissed. I believe there are no qualified engineers in service center.

I want to convey disappointment, dissatisfaction from the customer support provided by oneplus.
