Last month I posted the problem and here is the resolution:
I bought the Deltas from Audi A. Eventually I moved to stronger aids and gave the Deltas to a new user, my husband. He had them programmed by Audi B who is associated with our ENT doctor. By then Deltas had been replaced by other models and Audi A closed his practice and retired.
Then the dog incident, an I-told-you-so moment.
We bought another pair (didn’t notice a lot of singles!) on Ebay sold as used/demo. The seller seems professional and honest.
Audi B hearing the word “internet” refused to program one of the replacements. I don’t get it. He did not sell the originals and would not lose a sale now since Oticon no longer makes the Delta. Is this a common attitude? Over $800 is gone and we are worried!
After a bit of hand wringing we got in touch with Audi C who happily programmed the Ebay aids for a much lower cost than Audi B and did a better job too.
If there are any lessons to be learned here I don’t know what they are. I don’t even know who’s to blame, the pup or the spouse.
