Charges

I keep having $2.99 or $4.99 charges on my Apple account sometimes weekly, sometimes multiple times in a day, and I can NOT find out where they’re coming from. I’ve looked and cancelled all my subscriptions, I hardly play any games on my phone anymore and the only way I was able to stop the charges was to disconnect my Apple account and my bank. So my Apple account looks like there are charges that are ringing up and not being paid but I don’t know what they are or how to stop them 😬😬😬 Please help, I’m not great with technology unlike most folks my age and I’m really not trying to have a negative balance on any of my accounts.
