Oh my goodness! I know that getting a bill that is $800 higher than expected would be super shocking. For issues like this, we do have a process to check with the warehouse to see if it was just missed in a check in. Did you already speak with our customer care teams about this? If so, do you know if they filed a handset research form for this? If they did, you would have received an email from our research team letting you know the findings of the investigation.
Have you reached out our Tech Care folks to have a handset research form filed? We'd just like to make sure you get some assistance with this.
