We found this site very useful as there are a lot of non payers within the VoIP community. This sites Aim is to rid of all the non payers and for that reason we support them greatly as we also think its time to throw out the trash. Support the company by providing information on non payers or share it with ourselves and we will be sure to have it posted.

please be aware of company Interec.
We paid them prepay 7000$ after what they said that have very little capacity for route and can’ t give us dedicated capacity.
Our traffic went to them with very little amount, when we asked to send our prepaid money back and leave only 1000$ for traffic they just gave promises and dissapeared. when we announced their name in Linkedin forums they closed our traffic completely.
Company Tarasol Telecom http://www.tarasol.jo/ has outstanding debt of $ 44,000 .
All our negotiations didn’t give any results. Now they ignore all our requests, but we know that they still in VoIP business and they still have some traffic flow with some companys.
The above are some examples of what to look out for. Hope this is useful information and please send any other information that can help STOP fraud.
