Gonoise.com — regarding colorfit smart band

Address:

New Delhi, Delhi, 110018

I've a gonoise colorfit band. Today in the morning, when i was strapping it, i found the sensor cover present at the bottom of the band was not there.
I can assure you that the band wasn't injured or damaged by any means.
Also, the band sometimes stops responding sometimes, once in a week.
I'm not able to use/wear it.
I was pretty happy with the product till now, as i had no complaints.
Please help me in this regard.
My name is pulkit gupta.
