nirvantel company exits or not i agree with you ,these things are just a way of tricking neplese living in the US and they do not have proper info about the company and specially the CS people they irritate you so much ...some of them even call late at night when you are sleeping from cell phones and landline nos. they are selling products or what the hell ..can't figure out ..im really irritated and will have a few of my friends do something about it and i hope they are not tempering with the CC info they get over the phone . Nirvantel needs to professionalize rather then personalise the event of selling calling cards over the phone ..specially the females bugging us with calls and emails . we would like to request owner of NirvanaTel.com, and the owner RohiaLohit to check on the problems before these things get too serious and may get black listed very soon in the US ,as it is already having a bad reputation with the price and poor services and more over with little info about the company and employees calls and emails , don't personalise your company .Have profesionals work for you and not sick callers knocking 24/7 at peoples residence on personal interest.
