I have had a problem for months with a hissing on my landline and have written to Meo many, many times but got no reply!
FINALLY, someone telephoned me and after much switching on and off of equipment and "Please Wait"'s, it was decided that my phone had a fault and that the chap would send me a new one within 5 working days.
Much to my suprise, the new phone arrived, and on time! BUT
The man also asked me to return the old one and said that there would be details of how to do that enclosed with the new phone.
There was not!
As I cannot contact MEO by email as they have hidden their address so well, I am writing this on here so that anyone who is interested can see that I WANT to return my old, broken phone to them BUT DO NOT KNOW HOW!
