Favours?

I’ve done a bit of research surfing the internet, taking tips from my auntie and other reddit/ internet websites, but i’m still pretty confused on how to do this: I’d like to make a pact/ ask for a personal favour from someone/something, but i don’t really know how/ what to do. In the past i’ve attempted to perform rituals, drawn pentagrams, used candles, incense, ouija boards but I can’t contact anyone other than my “grandad” on the ouija board, I wasn’t convinced it was him as the things he said seemed really random and out of character, but besides that, I’d really appreciate some tips/advice on how to “ask a favour”/“make a deal”, as everything I’ve already tried hasn’t seemed to work.
