I always wondered which people phoned these things.
It's like the adverts on television late at night. Some nubile young woman is bouncing on a Space Hopper, asking you to text your postcode, and in minutes you could be texting with exciting girls in your area, and all for the bargain price of two quid a pop.
Still, whatever floats your boat...and lessens your bank balance, must keep some suckers happy.
