CCbill upgrade accounts

I have a niche adult dating site utilizing CCbill payment services. The site uses vldpersonals as the script. We have free members and paid members. There are 3 payment types users can choose to upgrade to: 1) A trial that rebills monthly after 3 days if not cancelled. 2) A 3 month recurring payment 3) one time payment Currently, whenever a user upgrades, it works fine. However, when a user cancels and their membership expires, or the 3 day trial finishes and they are rebilled at the higher rate their accounts paid membership expiry date or membership (free vs. paid) type does not automatically change. This is what needs to be fixed. Let me know if there are any questions.
