Charged for sim i didnt want/asked for

Mtn is the worst network ive ever came across.Ive been with the network now for 11 years no problem but when it comes to their contracts its a nightmare.In February i was contacted by a call centre offering me a tab with a sim card 500mb data for R59p/m or a 1gb data bundle for R89 p/m.I accepted the R89 bundle.I told them im not interested in anything except the tab and sim.Eventhough i told them that they still send me 2sims charging me R89 per sim.I contacted them about this only to be told that i must just pay it.My acc was paid upto date bt it was still suspended.I contacted mtn retention dept to be told i must pay for cancellation of the other sim.My question was why must i pay for something i didnt want in the 1st place.I emailed my docs 2randall in the pdf format he requested.Last week i emailed him again but till this day i never got a respond from him. The acc was handed over Hammond Pole att.Ive spoken 2 two of their agents which were so rude to a person.as i explain my situation to them they just tell me you must just pay the amount.Then they have the audacity to disconnect the call whilst im talking to them.The call centre made a ***** up with the contract now i have to come up with the money and just pay mtn.These big corporations really abuse people and make millions from *********** people. My advice to people think twice before you take out a contract with mtn.And if you do triple check the contents upon delivery and send it back if you notice theres extra stuff in it otherwise you end up paying way more than you originally agreed to pay.I will never take out anything with mtn.They either dont respond to your emails or make contact but can hastily send your acc to their attorney's.
