piztaker:
I did this offer. Got my credits within 24 hours. I then cancelled by phone after 3 weeks no problem.
same here, got the creds overnight. piece of cake to cancel, really helpfull staff.
the cancelation number can be a bit hard to find though (for obvious reasons) but a google to the site with the martin lewis bloke (can't remeber it at the moment) and it's on there.
probably one of the best trial pay deals i've used to be honest, a good helpfull site, good credit return and easy to get out of.
you should get some sort of confirmation email from credit expert, send this to WGT via the link in the offers page if you don't get credited and they should sort it for you. i had to do it once and they were really quick at sorting it :)
