The worst company to communicate with!

After multiple attempts to cancel my service and multiple confirmations that it would be cancelled and the box was dropped off Xfinity continues to bill me! They claim that unless you verbally give confirmation you cannot cancel!!! Despite then agreeing to a box drop off due to not being able to verbally give confirmation! How is that even a legal process. They assured me that drop off would suffice then when I reached out later said the opposite and keep arguing that until I answer answer a call WHICH IS IMPOSSIBLE for me,  I cannot officially have it cancelled. 

if you have ANY other option for a company to work with. Please go with it.
