So you go back to a store after you bought something and they change the price for it a week (or whatever) later?
Looks to me like you just want to profit from the discount.

If a car dealer has exactly two identical cars and you buy one for e.g. $5000 and someone else buys the other for $4000 a week later…
Do you really think the car dealer will give you $1000 back?
Get a clue…

I says DEPARTMENT, not business ticket.
There is a huge difference there.
Ofcourse it should be handled by their business department since you bought a license.

I ask you again. What is the real problem besides you being to try cheep?
