When I moved between apartments in NYC, Time Warner Cable internal systems got very confused somehow. I had working internet at the new address, and was only being billed for the new address, but the old address was still under my name somehow, so the people who moved in could not get service. I was called by a TWC sales rep to ask me to call TWC support to clear this up for the new tenants. TWC support transferred me between accounts-management and network-tech multiple times, they were all confused. Took about 2 hours of active question/response. (I went through it to make sure I wouldn't get some mystery/impossible bill in the future.)
