A technician lost some equipment when they were repairing my services and now I am being charged

I set up service in June of 2013 with Verizon Fios in NYC. It took about 3-4 different times for technicians coming out to finally get all my services to work properly and Verizon wound up comping my first month. In that time, I had a technician come out to repair my services. Well, he took my old TV set top box and replaced it with a new one.

Fast forward to June of 2014 when I'm moving out. I return the equipment in my possession and get my final bill stating I have a $100 credit coming my way. One month passes, no refund. Two months, nothing. August bill comes in(I kept checking online) and I notice a $626 charge for unreturned equipment. I call and they verify that I returned everything but one box, the box that the technician lost, or improperly stored. My initial call was 8/21 or there about. They assured me everything would be ok.

I come back from vacation, same thing. I've called at least 10 times now, about once a week. I've been promised its taken care of, that I'll get calls back and that this won't affect my credit, but none of these have happened. I have been told that I would be getting not one, not two, not three, but four calls back all from different representatives including one that never called me this morning 

My acccount has been put a hold on collections until they sort this out. That lasts for 90 days. 90 days from 8/21 is rapidly approaching and I don't want to get sent to collections. Further, it looks like they just hit my bill with a "Uncollectible (writeoff-activity)" which can still hurt my credit.

Who can I cotact that can actually help me out? Do I need to contact {edited for privacy} directly?
