After having a cell phone for two years at $50.00 a month I opened my Cingular phone bill this month and it was $505.00. I went way over my minutes on my plan because Cingular included calls that were made the month before. They call it deferred billing. A co-worker had the same thing happen this month. His bill is $300 over what it normally is. I can't get anyone at Cingular to provide a logical explanation. I think it must be illegal. I want to know how widespread this is. Anyone else have this happen?
