Verizon Wireless data usage, overcharging data, FIOS Columbus Nationwide

 This complaint is against Verizon Wireless FIOS service.  I signed up for Verizon because I moved to a rural area, on Sept 16, 2015.  2 days after they installed a cantenna, I received a message tat I am over my data usage.  I was on the 8GB plan.  I called and increased my plan to the 12GB plan.  2 days later I received another message that I am about to go over my data usage to I had to increase to the 20GB plan.  Meanwhile I had to shut off severals, data (on my iphone and ipad), and alter my life style.  this past Saturday, less than 2 weeks of installing the cantenna, I received yet another message that I have exceeded my data and will be charged $15.00 for each additional GB.  i called Verizon again and had my data plan increased to 25GB.  As soon as I did that, I received a message that I have exceeded my 25GB plan.  I give up! thank God I am within my 2 weeks trial which I am going to cancel.  BUT how can Verizon get away with this??? With no explanation other than the usage is coming from my cantenna.  i do not stream videos or anything else out of the ordinary.
