Mobile Talk...no Mobile Bull#@!$

Be very afraid of Mobile Talk, sales agent called my wife to offer a once in a life time offer through Telkom, R398.00 for 2 sim cards, one uncapped, one with 1gb for 24 months, with mobile router, with P Smart hand device, what a load of *******, (LTE A), firstly when I asked him to check LTE A coverage in my area, he said we were covered, When I asked are you sure the data package is unlimited, he said yes, many times, I called Telkom after we ordered the package, and they were not aware of it, not did we have LTE A coverage in our area, so what a DUD, anyway we are processing for cancellation will see where it goes from here, I called them to cancel, but obviously I am not able to do this on behalf of my wife, in this techno world are they so archaic.
