OnePlus India — Compliant for the microphone of one plus 8 pro

Subject:- Complaint letter for One plus 8 pro
Dear Sir/Madam
I am writing this letter to formally register a complaint regarding the sub-standard of the parts of the One plus 8 pro (Onyx Black 12GB RAM + 256GB Storage) phone that I received on 28.07.2020 from Amazon. I am very disappointed because of the microphone function is stopped working properly, due to which I have to put my speaker on while talking on the phone. It is very uncomfortable to use speaker while talking on the phone all the time.
During my official work once I visited to Prayagraj branch in U.P in the month February ’2021 according to them there was a problem in motherboard of the phone they said come again after 10 days to the part changed get. It was not possible for me to visit again Prayagraj at that time.
After that I visited to service centre Shipra Mall, Indirapuram Ghaziabad, U.P. They said you have installed Truecaller app due to which you are going through this microphone issue they immediately took my phone and uninstalled truecaller app and started arguing with me that phone is working properly but the problem was not resolved. I have been using one plus series mobile phone from last so many years but never observed such a kind of problem in phones and this kind of dissatisfactory behaviour and service from your service centre executives. One plus is a very renowned company and this kind of a behaviour is not excepted from such a reputed company, so you are requested to get my problem resolve as soon as possible.
I hope the issues I am facing will be addressed at the earliest.

Thanks
Manoj Bansal
