Roam 1 Cellular — Incorrect billing on International SIM card

I researched the plans by Roam1 Mobile on their website and hence opted for their plan as it seemed economical. But when I had used their card the recharge got over within 2 calls I made for few minutes. It did not just end there as despite several calls and emails, my concerns for correct billing were not addressed! Never use this service people. They are a lie and a sham!
