Facebook pages/groups get closed down weekly on Facebook. This give the reseller the opportunity to simply disappear. Portal urls etc are all shared freely on these pages/groups which leads to the service being isp blocked.
Of all the people you hear of being ripped off the majority of them are from Facebook sellers. There are very few cases of people being ripped of on TK
That Facebook seller has been around a couple of years and hasn't been shut down. The reseller I get my backup sub from had a great excuse and opportunity to disappear when the xtream problems arose. He stuck it out. As per my original point, not all cheap subs are bad. You're tarring everyone with the same brush.
