Bad Treatment from MBD agents

Dear MTN, I would like to extend my disappointment regarding my account that was handed over to MBD Credit Solution. I have tried to make contact with MBD on numerous occasions to make payment arrangement with no luck, I called their Center couple months ago, due to their high call volume I then opted for callback,I have never heard from them till this day. I then decided to call on 10July 2024, First attempt i got cut off while waiting on the queue, second attempt I finally got to speak to an agent, but the attitude I got from the agent was way over the roof,because i asked if there are any accounts showing on my name. I was told to drop the call and dial again cause she can only assist with 1 account at the time. we got into an argument and I eventually ask her to ignore my question and ask her to assist with my MTN account which she immediately hang up the phone on me,I thought maybe she accidentally dropped the call I waited for callback but there was nothing.I then went on Hello Peter to complain, then the office called me and requested Number that I called from so they can pull a recording, a day later I was told "Sorry we couldn't find recording" which i find it untrue. In all honestly I'm still seating with the unresolved problem. Í was promised to be called back to further arrange payment. still nothing. I find MBD ***********,dishonest and treating customers unfairly,cos my credit score is in danger while I'm making means to make it GOOD
