Hello how may I help you? Can you tell me how much data I have left on my plan? You have 20 gbs of data on your monthly plan. How much have I used this month? Unfortunately, I'm unable to check how much you've used. Ok, how can I add to my plan? I can double your data for an additional $10 per month. Ok, please do that. Sure thing. You now have 40 gbs of data per month. Ok, thanks! Not a problem.
