I missed a call from this number on a rarely used personal mobile of mine yesterday. I didn't recognise this code or number as one relevant to anything pertaining to me so I checked it out on this new interweb thingy. Apparently many people have recieved calls from this number and if answered, a man with a broad Northern Irish (the code is a NI one) accent claiming to be from Nat West is asking all sorts of personal details and claiming to be from Nat West Insurance services. Nat West have been notified and reckon it is someone phishing.
Be warned.
