Merging Accounts at same address


I recently had to cancel my original Fios account of 10 years because I needed static IP addresses.  We terminated the residential account to add the business internet only account.  Shortly there after they established the residential fios TV account.  I was told that I needed to merge the old residential with the new one but cant seem to figure out how to,  I am trying to get all the movies I purchased over the years back.

Please help!
