Tel 25

Hello Partners,
I had Interconnection with Tel25 Ltd., Van is the Acciount Manager from their Company, he used USA & vietnam routes from us around 700$ they used.
When i asked payment from them, they told me to offset but the thing is they are providing unstable routes with higher rates, How anyone can offset like this?.
I am requesting my payment since 7-8 months from Van, all the other employees even their CEO closed their Skype id, not reverting the emails too.
So please be careful with this Company. Do not open any kind of credit to this company.
His Skype id - live:sales_59280
