So I have a shared data plan and for once I was going to exceed my limit. My account description listed carryover as a feature but there was none available even though there should have been over 2Gig left over from the previous month. Chatted with support who opened a ticket. Now over 4 weeks have passed, I followed up and was told it takes time to work the ticket. My bill has a charge for the data overage and my plan description no longer shows carryover as a feature. I guess the ticket just tells support to erase the evidence.
