T-Mobile Coverage in Norfolk, England Problem?

Is anyone else having problems connecting to T-Mobile in Norfolk?

After last nights thunderstorm and heavy rain, I can't get a signal or connect to the network, even though I've switched off the phone, taken the battery and sim card out and even used the reset to default setting. I can't even get the emergency use only message!

I sent an e-mail to T-Mobile who say they are experiencing a high demand and I have to wait 5 working days for an answer!

If others are having a problem too, I know it's more likely to be the network / masts than my phone.

I have travelled more than 20 miles to work with no change and am about 8 miles (as the crow flies) from Norwich city centre where I usually get 5 star coverage.

So, anyone?
