Overcharge on my bill

I am over charged for my bill(16-07-2015 to 16-08-2015).My average bill for the month is less than R700.00 a month however when I got my bill for this month my bill was R2900.00.Please note that they cut my data during the month of July and I thought it wad because my contract with autopage was ending this month only to be saddened by the statemnent.I called the call centre and queried my bill and I got an agemt by the name of Daniel Mokoena who told me that I should write an email and send it to [Email Removed] requesting them to open my URL as it at my discretion and they will send me the feedback within 7 days.I did just that and I got the first email from service@altech acknowledging my email and that that my query might take up to 7 days max however I receved the second email and now its written that my query might take 8 weeks and they closed it as i need to send a letter with my ID.Why are they acting dodge on me now, the staff should know when and how long queries are resolved not for me to be taken like a fool.I am going to sue autopage, I want nothing to do with their service as long as i live.The closed reference I got from them is 822093.<br>
