Charge 2 not pairing, poor product/customer support

[PSK27]

I own a charge 2 since ~ 5 months. The screen cracked without any noticeable impact.
Fitbit support agreed to replace it with a new pebble (just the center piece without arm band, charging cable).
The first replacement pebble (#1) failed to pair with any device or fitbit account that I tried (iPad, iMac, Pixel, Pixel 3 XL, tried with two different fitbit accounts). The cracked old pebble pairs just fine with any device/account after unpairing.
Fitbit agreed to send me another new pebble (#2) to replace the defective pebble (#1). The second new pebble had the exact same problem, not pairing. 
Fitbit agreed again to send me another "new" pebble (#3). I am waiting now to receive it (and wonder whether I will just obtain #1 again...#1 = #3?).
The bottom line is: the refurbished replacement pebbles are defective (or the firmware?), and so is the customer service approach that just keeps sending bad pebbles around.
And I am stuck in what seems an infinite loop of getting "new" refurbished charge 2 pebbles. I need a way out, if fitbit has any pride in their product and customer support, they should fix this.

Are you removing the old tracker before you attempt to pair the replacement?

PS, it is not a Pebble. 

[PSK27]

Yes, I removed the old tracker, deleted it from the bluetooth history, etc, no success with any of these. Also tried to connect it to a newly generated account. No success either. 

PS: Fitbit calls it "pebble only" on the replacement paperwork

Seems they have some issues with the replacements, there's another thread about this: https://community.fitbit.com/t5/Charge-2/Replacement-Charge-2-won-t-pair/td-p/3099633/

In the meantime, I got the third replacement - same problem, replacement charge 2 won't sync with any device. Fitbit simply does not care honoring their warranty....

Plenty of threads on this.

Fitstly the cracking issue is widespread and secondly the pebbles they are sending out won’t pair.

Im being fobbed off with “we are working on it”. “We want you to have a great experience” blah blah blah.

They can’t fix a pebble that won’t connect yet they keep telling me they are working on a fix.

If I get no credible response today then I’m going to Consumer Advice first thing tomorrow.

The way we are being treated is an absolute disgrace.

How did you ge then to replace it because out the box mine hasn’t even turned on even after I charged it  so can you tell me how you got in contact with them

Twitter is best. Search Fitbit support. Or Facebook same.

Just an update here. 

We are in the fourth round of replacement. It seems like a game now. 

It is a bit surprising that all this customer support time and shipping costs are deemed cheaper than just sending us a charge 3, which would likely fix all the problems.
