Mondo MTN

I was contacted about data bundles contract. In the call the consultant spoke of a router as well but I did not receive it. He also did not mention that these bundles are split so when I received the sim and saw that it is not what I wanted, I called Mondo to request for a cancellation this was 2months ago. Last week I called to follow up coz they had deducted an amount that we didn't agree on. The consultant told me there was no record of cancellation and that she has emailed her bosses requesting for an immediate cancellation. I have not received any feedback since then
