how much data are you using? 

Any recent additions to your network such as a smart tv? device? 

You'd be surprised how fast data can be used with a smart tv. 

another thing to check is malware/virus/etc. 

I've been hit before with a virus that was using data and used almost 600gig in 2 days. 

Most windows and android device have a data usage monitor you can check.

Thank you for your response.  I was using less than 400 GB a month then in January it began spiking up to 1,407GB in Feb.  We do have a smart tv, but do no streaming, downloading movies, etc.  No other new devices have been added since last June when we purchased the TV.  I do have a ticket in to Xfinity security who will help me change the wifi password tomorrow (I hope! ).  Have a great evening.
