i tried to add the number of the West brom Building's society's HQ [which is 0121 525 7070] but my submission kept being rejected because (1) first try - although I copied the blue verification code, the submission kept refusing to recognise it ; and, (2) secondly - because i had come through Google.
I have used this site a lot and wanted to give back as there is no non-geographic number for the building society and I guess that will stay the same. Sad
