consulted from Rewardsco.com company **** to me.

I received a call from one of the consulted from Rewardsco.com, saying my mtn contract is due for Renewed that was Aprill. they said to me i will receive the same package that I'm getting which is 20 anytime data day and 20 anytime data at night which is 40 data every month with R147 a month which is less than what you are paying. I than agree to that package. but what I'm getting now is not what they promised me am getting 10 anytime data and 10 anytime data which is not what they promised me. when I called them, they said they will listen to the audio they said the person who called me and assist me was wrong by misled me with the wrong information and from they're side they can't change the contract. right now, I'm stuck with the data that I can't even last for a month like before I have to buy data before month end because the consulted from Rewardsco.com company **** to me.
