OnePlus India — one plus 7 mobile

Address:

One plus service Centre PVR complex Saket New Delhi, New Delhi, Delhi

I bought a one plus 7 a month back and since i seemed to have a setting issue i went to the saket service centre in pvr complex. My complaint was simple 1) instead of sms's i was receiving notification under which a whole lot of sms came with no pop up, 2) why do i have to manually switch to roaming when i travel. The gentleman at the counter claiming to be a trained technician inadvertently changed the setting resulting in in a problem with my emails with no notification happening. While the earlier problem seem to have been solved a new one had emerged which five hours later, they are still not able to resolve. The manger of the service centre amrita was ineffective, the regional manager
North mr akrit. Was useless. My andemand was 1) write me a letter acknowledging the mistake alternatively give me a new mobile. I demand an inquiry into the matter
