facing problem in adding new pixel setup into my website.

Hi there,
I installed pizel on my website using this plugin. but for some wierd reasons my facebook account got disabled. now i dont have the access to my business acount. i created a new account and wanted to set up a new pixel but when i try to do that or try to verify this domain in new business acount it gives an error message that this domain is already verified on another business acount.
My account was disabled due to age issue, i dont remember what age i set but facebook disabled my account telling me that your age is not enogh for advertisment on facebook.
Please tell mehow i can remove whole setup totally as there were no pixel code or event code ever intalled.

Thanks!
