Help, i've accidently changed

Help, i've accidently changed my data plan to pay per traffic. i want to change it back to monthly but it says i have to wait for one month can i change it back to monthly without waiting for 1 month ? Pay per traffic is eating up credits too quickly :( Please help me!

No problem. :-) I'd changed your data plan to Subscription and reset your changeable date too. If you'd like to change it back I think you can do again.

Thank you so much!
