Nano Hearing Aids Hearing aids advertised as "invisible" are highly visible.and after disputing charge, weeks of calling reaches nobody Arizona

The $249 charge to Citi Visa for the Nano Hearing aids was disputed back on August 25.   Prior to that, I had  asked many times for normal return label with no response.  I have called their "refund specialist" number 855-338-1602 five or six times a day for two weeks without ever reaching anyone.   Their recording says "No support agents are available to take your call.   Please call back later."  

Calling at all different times of day on different days gets that response every time.   I have experienced poor customer service many times over the years, but nothing approaching as bad as this evasion technique.  

They do answer the number for purchasing new hearing aids, but those people have failed to send a return label.   Amusingly, their copious materials do not show a real address.   I urge anyone not to make my mistake.    Do NOT buy from Nano!
