Hello @ASIF169,
Thank you for your post and welcome to the Community Forum!
For information about downgrading your business account to a Personal account, I would advise you to contact our customer care department who can help you further. You can do this by clicking on the contact link at the bottom of every PayPal page to check what your contact options are. You can also contact us through Twitter direct message or Facebook instant message.
I hope this helps.
