My name is Mithun Patel. I got extra bill for US international call which I did not now that US is included in free international call.
Please help me how can i remove extra charges.
Is it the free 1000 international long distance minutes you are referring to?
If so it is only to these select countries:
China (including Macau)
If you made calls to the US and was unaware unfortunately there is nothing that can be done because you made the calls so the charges would be valid.
If you will be calling the US often you might want to consider the unlimited US add-on, you can get more info here.
