overage letter

Hello,

I have just received a letter saying I am over my 250 gigabytes.this is hard to believe since we only use it for Netflix and email. And also the internet intermittently went out during the month for hours at a time. After reading some of the forums it seems that the meters cox uses are faulty. This makes more sense to me. In fact some moderators inn some areas have offered to return anyone who changed their data plan based on this letter to the original plan with no costs.

Also I was not advised of a limit on my plan when I signed up via phone. Thank you. David
