“I cant complain about the hearing aids I bought, but a few weeks ago I went in to buy a little plastic tube that connects the ear bud to the aid itself, ( keeps coming off) The receptionist told me she couldnt sell me just the tube, I had to see the Dr for it. I explained I could cut and fit it myself, She insisted I had to make an appt. I could not see paying for a Dr appt for something as simple as I needed. Just another way to get a Dr visit as I see it! ”
