Gross misrepresentation

When I engaged in my data contract with MTN via your company I was informed that a spend limit of R1.00 would be put on my data usage, which was clearly not done because now three months later, a debit of almost R1,600 was deducted from my bank account. A promise was made to request the recording of the engagement and revert to me, and a week later, I am still waiting. I hope never to engage in a contract with Mondo Mobile ever again because of gross misrepresentation on their part.
