MBD inc are *****s

You must watch out for this company. I was handed over by Vodacom to them. Made payment arrangements and kept to it. They call you up to 3 times a month at R28 per call that is added to your account. Last month my outstanding balance was R368 and then I can close that account. To my surprise on the 28th I made a payment of R400. They called me on the 28th stating that my account is now R420. I refused to pay. On the Morning of the 29th Feb 2020 they call again. My Vodacom account is now R495. These people are ******* and will charge whatever they feel. As of today they can harras someone else.
