MBD Harassment

I have 3 accounts that have been handed over to the above company and from the onset I would like to state that I'm not disputing the debt owned. My concerns are that the company call me Monday to Saturday every single day in on public holidays from 07:00 am in the morning.I have made arrangements for a debit order to go off which is on a system they have but still get a called every day. The consultant claims that it is a payment reminder but then tries to bully me into increase the amount after explaining my current situation .At times the consultants will ask me how long do I think it will take to settle the debt with to proposed amount. I will than finish with that consultant and after 13:00 pm I'll receive another call. They would then call family member or friends that I don't have contact with anymore at the same times as well. These names and numbers were never even supp**** to them. They will phone at 7 as mentioned but if you try calling them back if you miss the call, you will get a message that their hours are from 07:30 - 20:00. If you call back after 16:30 in the afternoon the same message comes up. This is the same on Saturdays and public holidays. Again, I'm not disputing the owed amounts but why with the same Company I receive one call for the Capfin debt but for the ABSA debt I'm harassed. Every time I request the numbers that are not relevant to be deleted, I'm promised it's been done and the next day the people get calls again. I received a message to confirm the numbers I want removed via a link but it will send an OTP to that number to confirm. If the people are already frustrated by the calls know they must still click on links that look like a Phishing ****. I have on numerous times requested to speak to a supervisor or manager to ask for assistance with this to no avail, I rather get a call from another agent repeating the same process. I have also logged a complaint with The Council for Debt Collectors.
