Also seeing spikes causing extra charges on my accout

October 300 gb November 600 gb December 1.3 Tb??????

 Customer service was not helpful at all, rude disrespectful and refused to help. If this continues  like this I have no choice but to end my service. This is 100% not my usage, I have been doing the same things on the internet for 3 years and never exceeded 700 gb.
