I updated my iPhone 6 & Apple had quite a few bugs to fix but meanwhile my phone kept kicking me out of my Wifi & I was using my data.
I think that Apple should credit people whom had this problem.
My data still has 13 days left & I only have 25% to work with.
I don't know if I'm more upset w/Apple for having the issues or Verizon for not doing doe kinda credit issued back to customers whom have clearly call & requested help with my Wifi dropping off & I wasn't aware of it..
It's sad, but unfortunately you probably have better luck building your own cell tower for data, then getting reimbursed by Verizon. Something similar happened to one of the lines on my acct.
