We paid £3,500 about 6 years ago for 2 hearing aids for my husband. We were told he had profound deafness in 1 ear and loss of hearing in the other. Wr obviously wanted aids that would give him the best outcome. The specialist in Boots only offered these expensive aids assuring us that they would work. 6 years on my husband hasnt wore them for over a year as he couldnt cope with them. They made his hearing more difficult. We did go for his annual check where the aids would be altered on the computer. My husband wzs told pn pne visit where it wasnt the usual person that he had a blockage. He started i haling menthol crystals and his hearing, though not perfect, is manageable. Boots will not consider a refund of any amount. £3,500 is a huge amount to lose for us. Unacceptable.
