Rebtel = Spam

Attention: Rebtel is a spam to me and my friends!

I thought Rebtel was great at first, until one of my friends in Vienna, Austria received his highest phone bill ever, 95 Euro, for â??calls to New Zealand.â?? (I live in New Zealand.)

He has never called New Zealand directly. He used Rebtel number I sent him. It looks like a Vienna local number, 01 253 892 101. The calls were supposed to be free according to his calling plan. Instead he was charged 95 Euro for those â??local callsâ?? at international rate.

How could a Vienna number show up as a New Zealand number on his phone bill? I have searched on Internet and found out I am not the only victom! Now the question is how to stop Rebtel so that it will not keep ripping off inocent people! (Please correct me, and tell me I am wrong.)
