Fren Mobile-8 has raised for the rate (calling same provider)

I think almost all of you that ever live in Indonesia and have cellphone, u will know about this one Fren for CDMA handphone.
Now rate for calling same Fren is raised! for 2 minutes is Rp1100,- before that Rp550,-
after 2 minutes, for each minutes is Rp14,-
Urhhhhkkk i dont know about that before my mom told to me like that, and before i check in the fren mobile-8 website.
After that i got all the data about price for calling to same provider or other provider.
Because that, now i inderstand that why my credit(pulsa) so quick to buy credit again.
For Fren Mobile-8, please give the customer infromation about that. Maybe the other from me still don't know about that and they just assume that Fren has play with the rate.
