vodacom misleading clients with so called discount

i have upgrade my contract with vodacom in 2018. february 2019 a company called mondeo phoned me with a discount on my current contract and the router, both discounted and more value for my money. i have clearly asked the operator if this is another contract as i dont want a second contract, one contact is adequate for me as i am a single user. she said no, this ia just discounted prices because i am a long and valued customer of vodacom. end of february i have paid the normal account and should have since end march pay no more than r369 per month, not a cent more, according to the sales rep. end march they deducted r1120 from my account. after querying my account the consultants informed me that they have actually sell an additional contract to me and not a discount on my existing contract. they have also send me 2 new sim cards, while the sales rep said they will courier my new contract to me via rams couriers. after consultation with vodacom, about 10 calls later, they ruled that i was in the wrong, i bought a second contract, they were right by informing me as such, which is not true. i bought a new contract after i clearly stated to the lady that i don't want a second contract. they refuse to cancel any of the two contracts and insist that i must keep both with a monthly account of roughly r1200. i strongly urge anybody not to deal telesales people from vodacom, if something goes wrong you cannot go to a codashop to sort it out, it must be done telephonically and the client always lose as they dont want to send the recording to you, it stays the property of vodacom and to refuse such offers as they mislead the clients by choosing words that sound as if it is discount and not a new contract.
