Utility collection letter addressed to "Occupant"

(MA)

I moved into my apartment a few months ago. Recently, I received a collection letter from a utility company addressed to my apartment, but in the name of "Occupant". The start date of the collection is a while before I moved into my apartment. The end date is a few weeks after I moved in. Since moving into my apartment, I have used this utility but have paid them in full from the date I moved in. Should I contact the collection agency to explain that I have paid in full since I have been living in my apartment, or do nothing since the letter was addressed to "Occupant" and not in my name? Thank you.
