missing equipment

I rec'd a bill for $120.00 for equipment on

my old account number..[Edited: "Personal Information"]..the only equipment I had was a "Flex" unit which I returned to your Crystal Lake IL  store.  The agent at the store stated it was outdated and he could not find it on my account.  I do have a gateway sent when my account was updated  [Edited: "Personal Information"]. Is this the piece you are looking for?
