Extremely poor service

Whatever you do, don't ever take a deal with Mondo mobile/Telkom. We took a phone and data deal, the data doesn't last at all and I know it's not possible to use all that data in such a short space of time when I don't even have social media besides WhatsApp. They overbilled us with 800 after saying the contract is 320 and when you try to call, their consultants don't answer, and when they do, they can't actually tell you where that bill came from. They debit your account and then sms and say the money didn't go through. After checking their system they see that the debit only reflected after 9 days, how is that even possible and then they want to pinalise you for a late debit for 200. This company is a huge **** and they must stop what they are doing. Very very poor service, save yourself a headache and don't get any contract with them.
