so i have not been able to update apps on my phone what do ever, every time i do it says "there is a billing problem with a family members previous purchase" im not two sure what to do i have left the family i was in,

I used to offer a set of suggestions based on Apple documentation as to how to resolve this, but as indicated by the officially Recommended solution in this topic --> Apple ID blocked because of billing probl… - Apple Community

you should just contact official Apple Support about a "billing problem" and let them help you.

Click here --> Choose your country or region - Official Apple Support Select your country, then a product. If you don't see one that handles your issue then keep experimenting with selections until you reach one that gets you a chat session or a telephone call and get the representative to redirect you.

or:

Contact Apple for support and service --> "See a list of Apple phone numbers around the world." - Contact Apple for support and service - Apple Support
