OnePlus India — Worst Experience with One Plus 8T with in 10 days of Purchase.

Dear Sir/Madam,

I had purchased one plus 8T mobile in the month of December-2020 on 23. Previous to this mobile i had been using Iphone since 2009. Upon friends proposing i changed to one plus and my experience is very worst. After 10 days of purchase issues in the mobile started. I even took mobile to service centre and they simply restored it to factory settings and i lost the entire data. After it worked for couple of days and issues started again. I tried to reach customer care and they suggested to clear Cache. After performing clear cache also the issues remain same. I tried to reach customer care and they are suggesting to contact service centre. My sister also purchased same mobile and her device dont have any of the issues. Other brand products are very good and why should i purchase one plus with 43000/ when performance is worst than competitors.The below are the issues

1.Signal drops suddenly and unable to make calls.
2.Unable to merge calls, only first person is able to hear and second person is unable to hear calls when connected.(Network conference calls is enabled)
3.phone switches off when call is received automatically and unable to know who has called.
4.Phone gets hanged and unable to perform any of the options. I need to hard restart the phone.

I am very much dissatisfied with the product and request you to please address these issues. I literally don't want the product to be repaired as it is new one.

Request you please address the issues as early as possible.

Thanks,
Srinivas
