I haven't been with them in over 3years because I owed 90 on my account and when I rang them to sort out payment I got the height of abuse from the woman I spoke to and because of her rude attitude I told her they could whistle for their money..didn't hear anything for 3 years and now they're hounding me for the 90..they must be strapped for cash if they're still annoying people after so long!!!!
