No reception in office in central London

[Anonymous]

I have been an O2 customer for a few year. A couple of months ago my employer moved to a new office in central London, EC2A.

Since then, I get no reception on my phone in the office. Either I get 1 bar of signal, and I cannot make calls as they always break up and drop within a minute, or I get no bars at all and my phone is not even on the network.  The O2 map lists good coverage throughout that area, and indeed the signal is fine when I am out on the street.

Is there way to fix this? If I can't use my phone for 8 or more hours per day there's no point in remaining an O2 customer.

Thanks. The FAQ doesn't say straight out, but I gather from "If you've got TU Go open and running on a few different devices, they'll all ring.." that what I'll need to do is open up tu go when I get to the office and leave it open all day? Otherwise it won't ring.

Yes that's correct.
