MTN Black Friday a con!

Customer service a joke! MTN advertising a 200gb+200gb Black Friday deal for R599. The deal is advertised on big posters in the store, however, the agent in the storesays that the deal is "online only". When you go online there is no deal to be found. MTN so-called "customer service" keeps me holding for 15min and can't help, tells me to phone their sales division. Their sales division can't help and tells me to phone customer service. Product being advertised but it doesn't seem like a single employee of MTN knows how to sell it!
