Overcharged with a spend limit of R0

<p>I received my bill for April for the LTE 30GB package that I have with you. However, on my bill there is a data usage charge for R1121,39 of which I have no idea where it came from. I then contacted your social media team via twitter to get more information on where the charges are coming from and was told that it is because I have used more data then what's i have, which is impossible as I made sure that my spending limits are R 0 and confirmed this in store when I took out the contract. Therefore, I refuse to pay the outstanding amount and will take it further if need be as i do feel I'm being charged for data we never used as we will always get the notification that we are out of Data when we try and login and then only use the night data. </p> <p> </p> <p>It it would be appreciated if the charges can be reversed and then I will make the payment for the next month. Alternatively, I will take further action as i have proof that my spending limit is on R0.</p> <p> </p> <p> </p>
