I originally ordered a HD151 on line together with Wax guards and Batteries. I paid by card, but it took an odd amount, and only the batteries and wax guards showed on the order confirmation. I phoned Hearing Direct and was informed that there was no record of me ordering the HD151 hearing aid, which meant I had been overcharged £117. She told me I could reorder a HD151 but it was not in stock, but they did have a HD150, which was, according to her, identical. I ordered this item and was charged a further £169. The lady said she would look into it, and get back to me regarding the overcharge payment - but did not. I few days later I phoned again, and got a different lady, whod did look into the over charge payment and immediately organised a refund. She also told me that the original wax guards supplied for the HD151 would not fit the HD150 (so obviously the hearing aids are not identical), and arranged to send me the correct wax guards free of charge. I am very pleased with the HD150 hearing aid, which is a basic model, and will almost certainly purchase a more sophisticated model for both ears at a later date. I started with a very bad experience using Hearing Direct's Website, followed by a less than helpful phone conversation with the fist lady. The second lady rescued the situation. It is imperative that Hearing Direct fully investigate the problems with there Website, bu also ensure that when phoned with problems, the problem is sorted out quickly and efficiently, and ensure return phone calls are made. They have a good product - ensure the service is equally as good.
