Over billing on Data Usage.

<p>Service request S3-GV028-8T9S0 was logged on the 12th of May, and yet no feedback has come forth.</p> <p>Invoice number B***, shows R 1,524.72 bill for data usage on cell phone number *** for the month of April 2016.<br />April 2016 was also the last month on contract for this number, the contract was terminated and its been on prepaid since 1st May 2016.<br />For the full duration of the now expired contract I have never paid more than R75.00 for 1G data on the same number, since it was actually capped.<br />Now, I need feedback as why was it billed R 1,524.72, on the last month of the expired and non-renewed contract? As I am certain not to have used that amount of data during the same month.<br />Please contact me on my primary number.</p> <p> </p>
