refund because information has been hold back

I just bought Appointments+. The reason that i bought this plugins is due it intergrates location of my employees. In order to activate this addon, i have to upgrade my account and pay extra. Ofcourse i am not going to do this, these are simple marketing tactics and i am not going for it. The way how you sell this plugin is wrong!

I want my money back and i will delete this stupid fraude plugin.
