Another Indian scammer - this one called "Arthur". Why is it always Indians who try to scam people? Appliance insurance scam - asked for a postcode - I gave him one 100 miles away and he is so stupid he did not realise this is not the same as telephone STD code. Try to waste as much of their time as possible. These Indians are so stupid.
