Has anyone successfully refunded their mistaken purchase?

I have a ver 2.0 perpetual license, and I wanted to upgrade. But all the plan options were so confusing, instead of upgrading to latest version, I ended up picking annual plan for ver 2.0.

So I basically paid for what I already have. I have contacted customer service, but I'm curious if anyone else has successfully refunded their purchases before.

From where I am, the subscription is a lot of money, so to pay that mich and not get what I actually want really sucks...
