Tried to change internet plans and ended up created a second account.

I tried to change my internet plan but for some reason the system instead opened a second account at the same address. It says both accounts are active so I am worried I will be double billed. I don't want to loose my original account that I've had for 6 years and have Premier status which includes Peacock Premium. How do I fix the new 2nd account. Can the new plan be applied to my original account?
