Telkom social media data

I purchased a R69 freeme booster bundle on 3rd Feb 2017. I called Telkom customer services this morning and was told that you must have online daily bundles in order to use free 500 megs social media bundle, what bull**** is that. So which means if your roaming on MTN because in my area in Nongoma there is no Telkom coverage, so that means I purchased this bundle for nothing because the network only roams on MTN. So now I have 500 GB of data that I can't use, I am so unhappy because now I have to purchase daily bundles everyday which is totally unfair by Telkom. This is the third time and having a problem with Telkom due to False advertising, we are loyal customers we pay for services that we can't use, and Telkom always refuses to give us refunds or reimbur*****t due to their non-compliance. If you guys do not have network coverage or data coverage in specific areas please stop selling your products and advertise your clients, stop just taking away our money and not providing service.
