Update to my return issue.
I contacted Costco Corporate and told them the story. Next thing I got a call from the Hearing Dept Mgr at my store. The one who didn’t like me from the get go must really hate me now. She is all phony sweet and says there was a misunderstanding and they can just return the aids to the Bernafon and get the ones with out the t-coil. I will be without aids for the time it takes to send them in and get them back. This was not a misunderstanding she made it real clear to my fitter who specifically asked her what they could do. Anyway there is still no answer about how many returns you get before you are black balled.
My Citi card is also my membership card. Even has my pic on it.
