transferred with PAC, number now not recognised

I have transferred from GG to I.D because my signal is poor. I am a front line NHS clinician and it is imperative I can be contacted 24/7.

It now transpires that;

1. ID coverage is even worse than GG, despite your coverage map say the contrary
2. My number, despite me using a PAC is now not recognised
3. I am unable to have any comms with ID support.

As if I am not under enough stress presently, utter failure on every count by ID.
