Charge 3 isn't registering sleep

[NiMhairtin]

I bought my first Fitbit Charge 3 end of August last year.The sleep tracker never gave accurate sleep information, I had bought the Fitbit particularly for the sleep aspect as I am a terrible sleeper. It worked say once, every two weeks. I complained to Fitbit who put me to a lot of effort to try and 'fix' it online but nothing worked and finally, after 3 months issued me a new one.

Guess what? This second watch does not work either! I am so frustrated. The shop where I bought it says Fitbit will only deal with complaints. I paid 165 euro for TWO Fitbit that do not function. Help please?

I have no faith in the product and want my money back! The service team make it so painful to complain trying to push solutions that simply don't work, reset, change arm you're wearing, put it on sensitive, wear it tighter/looser. I am at the end of my tether. Help!
