Hi murraymints
Tried the number you gave me - the usual automated voice - was going nowhere and gave up!
Almost immediately, I received call on my mobile and was, at last, able to talk to young lady.
Lots of guff about tests being done and would update me within 72 hours!
Played merry hell (sorry) and stressed my need for quick cure - she said in view of my need for phone for medical reasons, engineer would attend tomorrow.
Gave me her direct phone number 0800 444 1870
So, dear murray, thanks for your support in my "hour of need " - very much appreciated.
Now just a matter of keeping my fingers crossed.
