Core group non existent service or values

So my fitbit stops working .bought it 6 months ago. I have proof from store and credit card slip on the day it was bought. Because they can't read the date on the slip they will not process the return.

How is that even possible. ******* is all i can say.

So I call a Romandi a key account manager at Core. Promises I will get a call.back. nothing. Next step is to send email to fitbit in USA and then sue them in small.claims court.

They just don't care
