Awaiting refund??

<p>Since 1 Oct 2016, I'm not able to buy/load data on my phone (contract). Customer care cannot load data from their side either?? Solution department said it is a system problem and they will do a refund on my account as my phone was using out of bundle rate data for 1 month!!. I have been phoning customer care for 3 months now .....no one can assist me in this matter? They cannot find the so called refund that was logged and I am left with a huge bill to settle? Our local vodacom shop logged a few complaints, but no one can assist???</p>
