We certainly don't want you to feel cheated, and I'll be happy to explain how proration works. If you change your plan On Demand (today), your new plan is effective that day. Your 4GB plan essentially ended yesterday. For 2 days on the 2GB plan, you would be allotted approximately 0.129GB. What was remaining on the 4GB plan would not rollover into the new plan. It is best to either future date or change your plan on the first day of the bill cycle to avoid any proration.
