Clay Telecom — Worst communication services ever!!!

As a part of an official trip to US, my admin guy got me an international sim card from Clay mentioning that everything has been taken care of and i would have no issues using the same. And what can say after i started using this intriguing peice of technology. After 2 days all incomings and outgoings barred!!! Somehow the customer care responded being a Sunday giving me a lame reason as that i have crossed my credit limit of 5k rs and until i deposit more money they cant restart the services!!! How is it even possible that a post paid corporate connection be serviced like this !! Total disappointment !!
