Said was UK Government Financial Service or something similar and informed me that I had money which needed to be returned to me. He then asked which bank I was with and then asked for banking details. I rang off at this point, without giving details. I then rank my bank and a scam was confirmed and I had done the right thing by not giving details and ringing off. Anyone else who receives a call from this number must not give banking details and check their balance on the bank account - just to make sure nothing strange is going on.
