This just happen to me this weekend, November 16, 2014. I received a message about I reach my cap in Data Usage when I knowly know I have a unlimited data. Contact ATT and they insisted that I had not had unlimited for the past last billing cycle but when I log in it clearly said I had unlimited data. I requested to be transferred to a supervisor where he mention there must of been an error in removing my unlimited data. So now I have to wait 7 days for this to be resolved. This is unsatisfactory when I have been a loyal customers for over 7 years.
How has the outcome been to all those who lost their plan, where you able to regain it back?
