I don’t use it but they still take money from my account

I am so angry with these people. I think I must have looked at the gallery, but decided Foo Gallery suited my needs more. So I deleted the plugin. A year later I’m told they’ve just helped them selves to more cash. In the email they send telling you they’ve ripped you off they try and sell you upgrades, but nothing about how to cancel it. Just read a comment from someone who tried to cancel and they spammed her site. Stay well clear of these unethical people.
