Mondo *****

I app**** for 1 telkom sim 10gb for R99 but I was received 2 sim cards, I called the mondo call center and I asked why I received 2 sim cards instead of one. The consultant I spoke to told me that its buy one get one free. I was then shocked when I received my statement coz I was charged for both sims. I then called mondo again and they said they will investigate if I really did want apply for only one 1 sim card. They came back to me and told that they listened to the call when I made the application that I did apply for only one sim card. They said they will then cancel the second sim card and I will not be charged again. That was o the 7th of November 2019. But they still haven't cancelled that sim card and I have just received an invoice for this month, I'm being charged again. I'm wondering if this is how mondo tricks people, they give you something you did not want in the 1st place and pay for it anyway. Coz it seems impossible for me to get that sim card cancelled.
