Does megaphone charge for calls via Skype?

Today I accidentally stumbled upon a message about a person having problems with billing when using a 3G Modem from a megaphone for conversations on Skype. In the light of recent events “OPPS vs Skype” I would like to check whether this is true:

In short, the person made several Skype calls using a 3G modem from Megaphone to connect to it. After that, he discovered that Megafon charged his Skype calls as a conversation on Megafon tariffs.

In his post, a man leads a printout of the account. And he writes that he called via Skype.

If anyone has a 3G modem from a megaphone, I would like to check this information. The user's computer could be infected with a virus using a modem to make unauthorized user calls.

The story is too unbelievable to be true, but as you know, exactly what you do not want to believe happens most often.

Link to the post of the victim.

UPD. Please do not make a fuss, and who has the opportunity to check. because The story is pretty incredible, but the person indicates that the numbers in the account are numbers to which he made calls.
