Even with a spending limit of R0 I still spend more

<p>I received a bill from Telkom stating that I have used an R1200 of data on a package that cost R599 per month. This is even with a spending limit of R0 on my account, I was still able to go over the amount I am suppose to be alloacted. I then queried it to just be sent a copy of my bill with no explanation and then I raised another complaint that was solved this week as I don't answer my phone when they tried to call me. I can prove that I received 0 call and even received an SMS saying I did not answer my phone while I was busy on my phone. The consultant then just emailed me a breakdown of when the data was used. How is it possible that I used extra data after 12 when we have night data and most month have night data left. I'm still trying to get an answer to why there was no Cap app**** to my account when I requested that a spending limit of R0 be put on my account and why Telkom have spending limits when these are not enforced. I checked on my Telkom app and my permanent spending limit still indicated R0. What's the use of having these options and telling customers to make use of them if you are not going to enforce them. I refuse to pay the out of bundle cost until i can get an explanation to why the limit is on R0 but yet I was not capped. Then why not send SMS notification to customers notifying them that they are going to be charged for out of bundle. </p>
