Gotta say, waiting for a call from the cable company to cancel my late mom's service because Comcast forces you to talk to someone to explain why you're canceling, no matter the reason, is not cool.
True, but just picture the Comcast installer endlessly circling the cemetary, when they screw up the cancellation and instead schedule a service relocation, to your mom's plot.
In wrapping up my mom's various situations the only one I lost my temper with was the cable company. They insisted on an obituary as proof, though she had passed away just the day before.
