one of our accounts got shut off. I called comcast business support to make a payment.
1st prompt: new or existing crusty
2nd prompt: Zip Code
3rd prompt: tech support, billing....
4th prompt: account details menu
so comcast takes your phone number and zip code, then authenticates you into an account.
In this particular case it happed to not be my account. I before I realized what was happening, I heard info on last payment date/amount, total balance due. hung up.
tech support --> Human
name, address, phone number
three accounts pop (account from 1st call was not one of them).
tech support explanation was that phone number links accounts across all comcast boards (biz/residential).
