FAULTY FITBIT CHARGE 3 - 16 EMAILS LATER - NO SOLUTION

I have been emailing Fitbit about my Charge 3 since the end of SEPTEMBER with no solution to my problem. My display face is so faded / dull I can't read it unless I do so in an almost pitch black room! The responses I get are non committal and vague. I am told to "wait" - it is being resolved, but they cant tell me by when! My Complaint number #***7. SIXTEEN EMAILS LATER AND STILL NO SOLUTION.
