This is a response to Amplifies response A loose part on a toy is a choking hazard and H & S would be all over that.Why is acceptable to have lugs come off a hearing aid in an ear canal which necessitated two emergency GP surgery visits and nearly hospital.You say it is rare but the fact they come off is wrong let alone blaming somebody for pushing them in to hard. You then gave mum another style instead of offering a refund but they were completely unsuitable.Mum has narrow canals and they block up quickly within days and require filter cleaning.Mum cannot clean the filters as she has claw hands and arthritis as well as being registered disabled.You advise that a consultant checks she can fit and clean at time of providing yet it was patently clear by the state of her hands that she could not manage.It is wrong of a sales company to say get another family member to do it especially when Mum lives alone.Your latest offer to clean involves her taking the packet to the post office and sending special delivery which is expensive.Not really practical when filters need changing every 7 days so you would be without for several days per month.It is clear that these were not fit for the specific customer and should not have been provided but targets and profits before customers-Disgusted with attitude of customer services
