Wrong email

Today I made my Xfinity account after getting a plan and everything. Well once it all was said and done and said thank you for your purchase I realized my email was off by one letter . The email that was put in doesn’t exist and I even went and made that email right after to find no verification code . But I do not want to make another account with the correct email until I know that that one has canceled out. Any help would be Great because it said there was a appointment scheduled for the 5th but now I can’t check
