"Audiology apointment process"

In 2014 I was referred to Whipps Cross audiology by my GP for hearing teats and was fitted with hearing aids. Since then, on two occasions, I have attended a 'turn up and wait' clinic to have the earbuds replaced and the aids checked. Staff have been very efficient and helpful at all times. I now need a 'fine tune' appointment which my 'brown book' says I can book by e-mailing audiology or phoning (or faxing!) the hospital.Obviously as I am deaf I find it difficult to use the phone (and couldn't get through anyway) so e-mailed, and got an automated reply from something called 'Wood Lane' (when googled it appears that this facility closed in 2014). I have still not had a reply to my e-mail. It seem the only way I can get an appointment is to see my GP - wasting their and my time. Please sort out your booking systems, and the information available in the internet for existing (if infrequent) users..
