I can have my audiologist who services ReSound send them in to GN?
Jabra aids are exclusive to Costco, so I’m almost certain your audiologist cannot send them to Resound. Contact Costco and tell them that you were given the aids. Go with someone that has a membership (or call them).
If Costco agrees to fix the aids, you’ll need to pay the membership fee. I believe they charge approximately $150 per aid for repairs.
If you bought the aids from eBay and the seller did not say “parts only” (which means they are not in working condition), file an INAD (item not as describe). INADs requests almost always refund the $$$ (it has to be within 30 days from the day your items were delivered).
I wouldn’t buy an aid with rechargeable battery from eBay (used) unless the item offers the eBay optional 1 or 2yrs warranty (Asurion)
