UNEXPLAINED EXHORBITANT UNBILLED ACCOUNT

Yesterday, I received a sms notifying me that my unbilled balance was R1900 and that I was to call Altech Autopage regarding this. This morning I called Altech Autopage and enquired as to why the account was so high. I explained to the consultant, a lady by the name of Tebogo, that inasmuch as I was on an open contract in previous months whenever my data was depleted I would get the message reflecting same whenever I accessed my browser and would then have to purchase from my banking account. <br> <br> For some reason this was not the case this month and Autopage are unable to say to me exactly where the data is going to and why suddenly excess data is being deducted from my account without me having agreed to my usage being upped. What further irked me was my being told to complete a URL form to which a response will only be received in six weeks time from MTN. <br> <br> What do I do in the interim, as the source of the problem is unknown and can therefore not be stopped. Am I expected to accept that crazy amounts like R800 daily usage be added to my account when I am not using so much data?
