Rewardsco mtn *****

Rewards co contacted me for a mtn contract. When they contacted me the agent advised that the contract was 380 and nothing more. When i received the contract via the courier i received the phone with two mtn sim cards. 2 different numbers one was with airtime and tge other with data. I have contacted mtn to find out about this they said that i will need to contact rewardsco coz they are the company that opened the contract for me and that im paying for two contracts my bill came to over R600. 00 mtn cant do anything about this. I will be taking this further i cant get through to rewardsco cause tge line keeps on dropping after 2minutes. Im requesting the full call recording from start to end as im going to court with this cause this is *****. Im also working in a contact centre and if you dont give me what was offered on that day the contract is null and void. Somone needs to contact me asap. To get this sorted because im not leaving this so.
