Pathetic, nonsensical and down right unacceptable service!

I lodged a formal complaint with MTN on the 4th of this month already because I had received the most shocking service from their consultants and a team leader, I felt comfort writing to the complaints team because I was expecting that they would give my case the sense or urgency that it required, today marked the 5th working day since then and all I have received is the automated email that they send to acknowledge receipt of the email, which states that they normally try and resolve issues within 24 hours, its has been 120 business hours and I have not heard anything from them. I wrote to the complaints department regarding poor services, and now I am writing here to complain about their complaints department, no sense of urgency, zero accountability and appalling service seems to be the order of the day on all level clearly.
