Waiting for branch to ring back never do you always have to ring. Went into a branch in Wolverhampton to get new tubes assistant changed them put wrong size in then proceeded to tell me after she had thrown the original away so had to go to another branch. One of my aids started buzzing took it to the Bilston branch said they would need to send it away still waiting 3 weeks on always going to ring you back never do its always the customer that does the chasing. Suffering from headaches and earache from only having one aid can’t hear properly. Never had any problems when I had them from West Park Hospital. My advice stay well away
