Telkom has no respect for their customers

I purchased 20GB + 20GB on prepaid on Tuesday (22/05/18), after inserting the sim card into my router it tells me I'm out of bundles. I didn't connect to the internet at all. The following day I called and the call center agent contacted the person who helped me in the store. She assured me the issue would be resolved within 24hrs after I sent her the invoice. I emailed her on Thursday when I still had no data. Now a week later, I still don't have data and after calling this morning I was told to go in store for assistance. So now I'm supposed to take half day off from work to resolve this myself. I'm very disappointed with the service or lack there of, I'm receiving after I paid my money upfront.
