A few months ago I requested a data block on all the phones in our plan. The following month I had more data charges so I called to request it again. They assured me that all phones would be blocked. The next month I received another bill with over $400 worth of data charges. I called again to ask why I was still being charged for services that were supposed to be blocked. The told me whomever I spoke to the first 2 times did not "make a note" of my phone call and I was responsible for all charges. I was basically told that even with the block in effect I should follow my kids around and make sure they were not connecting to the net. Should I be responsible for these charges?
