Your fundraising plugin is terrible, I'm trying to make it work for 3 months now!

I've been trying to get this plugin to work for 3 months now, and every time I think it's almost done it has a new problem.
I can't keep paying you each month just to get the support to make it work, I'm not responsible for your plugins bugs and problems!
It takes your support group at the forums a very long time to solve a problem (even just to reply), and apparently, meanwhile you keep charging me for this time!

I ask you one more time for an answer to this topic

I'm not going to wait until you take the next payment again.
I bought a plugin and I expect it to work!

Thank you.
