Data gone

I have had this Telkom contract for almost 2 years. Only once before did I have to make a query because my data ran out a week before month end which was VERY unusual for me as I always carry it over.<br> Today is the 14th and my daytime data is GONE. All gone. Even though I only use it for work and Facebook. No downloads etc. I honestly I have no faith in this being resolved because the previous time you just sent me a usage spreadsheet and said case closed. Even though I didn't even understand all the numbers and columns on the spreadsheet.<br> I read that I am able to CANCEL the contract as it's just a data contract and I didn't receive any device with it. How do I go about doing that because I've seen many people complaining about closing accounts only to still receive bills months later.<br> Please advise. This is completely unacceptable, I have two weeks of work left and no data. I'm beyond frustrated mostly because I know you'll just say 'oh well' and not try to find out what's going on. Please surprise me and find the problem.
