Migration to Office 365 Still not complete 1 month later

My migration date was September 28th.  After having email issues I contacted the Cloud Solutions support and was told that my migration never completed and I had to be sent new DNS settings to change to make the migration complete.  That was October 24th.  Since then I've been on the phone with Comcast every day for 1-2 hours each day.  Ticket number still escalated to a Tier 2 - no call back, not communication, no resolution.  My last call was today at 1:30.  They can still see the migration is not complete and that the email I need with the DNS settings has not been sent but cannot tell me anyting other than that.  Told me to call back again tomorrow if I still don't have the email.  New email cannot be created and added to Outlook on desktop - at end of rope - please advise.
