Neotel can't add up data usage

I called Neotel to ask how do I get a total Data usage so to check on my 10GB package. You go to unused data usage and if gives you a total for each day but not a running total in other words it does not add each day up. They expect you to get a calculator and add it up yourself, how stupid I thought. I asked the consultant and after explaining they said please hold. He went away and just left me hanging for 5 minutes, the usual way call centers get you to go.
