Out of touch?

I hate it when people tell me absolute whoppers. I find it rather offensive that they think I might be daft enough to believe them. I was in conversation with someone whose company had rather dropped the ball and was messing us about a bit, and the other person said "We've been trying to contact you for a while..."

How? What with? Were they shouting on street corners, writing slogans on walls, sending out carrier pigeons, trying remote Vulcan mind melds? They've got my mobile and home numbers, plus email address. How could they try and get in touch and not have me notice? 

Well, really.
