So I tried all customer support channels to switch my plan, but I've had no luck until I came to the forums. I was PM'd by @FidoStephane and given some tasks (social media authorization, etc) to move forward with changing my plan to the 10gb special. I completed those tasks, but haven't heard anything since then, which was more than 6 hours ago.
Totally understand that all customer service and community reps are swamped with trying to deal with a lot of requests, so definitely not expecting immediate response to everything, but also want to make sure I'm not forgotten about given that I was being helped at one point. I worry now that my request, while acknowledged, hasn't been resolved and I've now missed out on the plan.
