I think we should be as quick to praise as moan!
I have just had a excellent experience with google customer services after having an issue with my Fitbit. It was disconnecting from the strap and falling off. The warranty was 2 years I'd had it 18 months.
They were great.
Freephone number- quick answer, asked questions and asked for a photo. Sent label to send it back with case number. One week later I have a new Fitbit.
They could not have been better or more helpful.
Who has been great for you by their customer service- Name and do not shame -praise
