After 4 months, still no resolve on a account overcharge

<p>I subscribed on a Telkom mobile deal which was a 5GB per month for R299/month. On 23 February 2016, I tried purchasing a 5GB bundle to no avail. Eventually I got it right. But when my bill came and I was charged for 3 additional failed bundle purchases (which totals at R 897). Please note that my account limit was set to R1000/month, meaning I can only purchase an attitional 2x5GB bundels per month. After logging a call at the end of February, this has still not been resolved. I continuously received the 'it has been escalated', where today I found out the case was just closed without any feedback or refund. I am also not allowed to talk to a supervisor or a manager regarding this issue.</p>
