Closed Account still linked causing problems online

I hae two accounts on my profile.  One was closed when my father died.  It is the primary account referenced on my profile.  I try to make the active account my primary and get an error message.  I've been on the phone for hours and even went into a store.  On the last call with an agent I was told he couldn't help me and that my issue needed accelerated assistance and i should hear from somebody within the week.  As you can guess, that never happened.  If this is not resolved this week I will be forced to close my xfinity account!!
