MBD Debt collectors take their clients for a ride, they are the biggest ********!!

They dont deserve even a negative rating. I decided to call them around June 2021 to make arrangements to pay for my wife's debt from OnAir TV that was handed over to them. There was no problem back then as they allowed me to make arrangements and we agreed on the phone that I would pay over 2 month (July and August 2021) and then I can call them to ask for a paid-up letter. Fast forward to last week (September 2021); Now I cannot call and ask for a paid-up letter because its not my account and my wife should be the one calling for it. Funny how it wasnt a problem when I was the one to pay for her account. Ok after dealing with a rude lady who refused to give her name and kept on dropping my call, my wife called MBD call centre and met the same lady who dropped her call as soon as she gave her the details. we kept trying to call until she met another Agent named Zukiswa who told us that we still owed R120 that will still be debited this month for collecting fees. This was never agreed upon in the telephone agreement at the beginning and they never mentioned any of this. So is it fair to go against the agreement? when I ask them this, they dropped my call. Never make a debit order agreement with them, they are ******!!!! Rather you deposit their money monthly rather than debit order!!!!!
