Do they cast spells ? Like make spells happen and it actually works like witchcraft ?

Yes

I dont get it ?? but, According to their website, / on their website - when you click the "Readers" button and in the ensuing the paragraphs last line they have a clause which clearly states: "Please be advised that it is against Catland's house policy to conduct spellwork on behalf of clients." ??

What about love spells? They charge?
