About deleting accounts and traces, if possible.

Yeah, I want to delete everything after two weeks of trying out these platforms. It’s just super boring and exhausting. Plus, I hate the fact that I've downloaded some crappy mobile games. I want to delete my accounts, but first I want to withdraw the money. Which is better to “burn” in this situation? Visa or PayPal (I hardly ever use it)? Maybe in the future I’ll consider getting back into this paid surveys stuff (I doubt it), with a new account, cheating consistently. Will my payment method already be compromised? Should I factory reset my phone? Try to delete data on Google (God, I hate having those puzzle games in my downloads)? What steps can I take on my PC?
