We informed them that we were ending the contract, giving them the appropriate notice period (we are moving to a different provider with vastly superior cameras who are much cheaper) but when we followed to to inform them that the contract had now ended and we were taking down their equipment they said that we'd still have to wait until they were ready to remove their cameras and that could take weeks. We took their cameras down, undamaged, and boxed them up for them. They were very aggressive and hostile on the phone.
