Moved to new plan without permission

Hi everyone — I’m wondering if anyone else has been switched to a different plan without their consent. I recently found out my plan was changed, and when I called to ask why and requested to be moved back, I was told my original plan “no longer exists” and that my only option is to accept the new, higher price.

This doesn’t seem right. I didn’t request or approve any changes, yet I’m being asked to pay more for essentially the same plan I had just two days ago. They did offer three free months as a courtesy, but after that I’d still be required to pay the increased rate — which I don’t feel is a fair resolution.

Has anyone else experienced something similar?
