I'm quite happy to waste the time of the guys who I have received calls from recently. They are total assholes and have been harassing people for years if my research into their phone number and company name is anything to go by. The actual (Indian, but the company is based in London) callers have been known to call and hang up repeatedly, insult or threaten the person being called when they demand to be taken off their contacts list ot demand to know where they got their information from in the first place etc.
