I am currently using an Iphone 4s, i use the Self-Serve App but it constantly says Error "we're unable to process your request. Please verify the information and try again." this happens to me repeatedly to me all day when i just want to check my usage. Everything else works for the other options, just the usage option. Is anyone finding this same glitch with their app? Is it just a software glitch or me! I will get my usage summary eventually but its just a pain when you have to try again and again over a period of time.
