I bought a clay Sim card for France and while which worked fine the first day, acted up a lil on the secnd and stopped all of a sudden on the third!! I had to make calls to their customer centre via payphones to get this recurring issue fixed! But there was no respite from their end. Those guys were not even concerned about the issue, infact kept on saying it will get fixed in a few hours, but they never were really empathetic about my problem. I am totally disappointed with their services and will ensure taht everybody gets to know of this!!
