Some weeks ago I checked facebook ads,. Didn't make one.I clicked on it & then i found that they are not free so I canceled. I checked my account settings, Opened options of payments. It is in my account settings with name facebook ads. Is it fine because I am worried that are they costing me? and I haven't put up any credit card number on facebook. Please tell that is it fine I am worried.I checked facebook campaigns too .Its says I have no notification!!I just get worried on small small things.IS IT FINE???.Because it is in my account settings and I haven't made one .
I HAVEN'T MADE ANY ADD!!
I just checked them . .& worried that why it is there in my account settings
In my payments it says "You have no funding sources associated with your account." and i haven't gave them

You have nothing to worry about if you haven't put your credit card or PayPal address or any other payment method to Facebook or anything attached to your Facebook account.

If you haven't put in any credit card information there is absolutely ZERO way they will make you pay. Calm down its okay : )

if you haven't provided Facebook with you banking details then there is no way they can be charging you but if you have put any banking/money details up on FB i would remove them just in case but they still would charge you for the ad anyway (only if you gave them your details)
