Thanks for sharing FreeOnes. Sorry to hear about your problems, but hope you don't mind if I'm kinda happy not being alone in this 

 If you succeed to cancel their services, please let me know how you achieve that, so I could pass the info to my customers. Thanks!
BTW, if anyone knows a good and reliable SMS/phone billing company, please inform me.
Also, all you guys reading this, please warn your friends and business partners about txtNation. I hope noone else will get into the trap named txtNation.
