The call flagged as Nuisance? so I let it ring. It went to answerphone. Message left left claiming to be from BOC with some very important safety information about industrial gas cylinders they supply our business and asking me to call back today. This is a domestic phone with no business or gas supplies. I didn't call back.

Caller with accent, from call centre, wanting to speak to someone who makes financial decisons in the company. Something to do with web presence on Google, but difficult to hear. Obviously trying to sell something, but not clear what.
