MTN you *******!

They don't even deserve that one star that I gave them. My two cellphone contracts with MTN came to an end at the end of November and I took out two data only contracts of R68 each but these people keep on deducting, R700 + (Dec), R400+ Jan, R400+ (Feb). I logged a complain but never received any feedback. You are the biggest *****es and I want my money back!
