Telkom SmartBroadband Wireless LTE data (20GB+20GB)+ a WiFi router (July 2017 deal of the month)

I am not happy with my recent experience with Telkom. After agreeing telephonically with Telkom (on the 31st of July 2017) that I would like to take the July 2017 deal of the month (20+20 gigs for R299), I received 10+10 gigs of data. The Wifi router was also delivered.

When I called in to enquire about the discrepancy, I was told that they see the 10+10 data option, and not the 20+20 that I agreed on. Also, they could not tell me why my option is 10+10. I sent a complaint through their website approximately 2 weeks ago. To-date, I have not received a response from Telkom.

I would like this query resolved, for Telkom to give me the data option that we agreed on telephonically, the 20+20 gig for R299 p/m (July deal of the month) immediately.
