@Ylt log into your self service account and see if the duplicate payment is showing as a credit there. If it is, PM is prepaid, thee are no refunds. If you as lucky enough to get a sympathetic moderator and get one. It takes approximately 1 month. So its better to leave it to pay for the next 30 day cycle.
If its only showing up as a pending charge online in your credit card acount. Ignore it, it usually clears up overnight. Welcome to the community. Stay safe.
