MBD Business Practices

MBD consultants.. they call me × 5 daily sometimes noone says anything. Worse their calls start before 7am. I told them I nolonger work, Unfortunately I couldnt pay what was required hence I was handed over. Told them I will try but they seem not to be bothered. All was told is that my balance will never ever go down cause each call and sms received will be paid by me. So i asked the lady how am I expected to pay for such when even my situation doesn't afford me that luxury. Her answer was.. " I'm just warning you". The threats we get daily ... that's not ethical
