Got a call - no message left either - from this number today at 1:51 PM. Tried to call it back and recorded voice says "this number is no longer in service, etc."
I hate solicitors calling me for no apparent reason and leaving no message just proves how cowardly they are.
Just had a call from them. There was a long pause and than some Indian voice asked for something that I couldn't make out so I hung up. Like Jenny said, there was alot of noise in the background
