I paid !39 for a pair of hearing aids from the Nano Ear and never received them. I tried contacting them by e mail, messenger and phone. The phone number was not in service. I spoke with Spotify who tracks their product and told them I had never received the hearing aids.
Since they would not return my money even though I asked for the order to be refunded and it was over the 30 day limit, I did not contact my bank.
After reading other reviews on line, I know now that this was an Internet Scam.
