3rd Complaint in two weeks

So much for the biggest credit bureau in SA. I complained two weeks ago and the lady that called me said she will try and get the issue resolved, she never came back to me to-date. 5 days later I complained again on this platform and I was told matter has been escalated like you always say to everyone. Complaint ignored as no one attended to it, very unprofessional. This is my 3rd complaint in 2 weeks, well I shall keep them coming until someone is competent enough to attend to my complaint. A clearance certificate and paid up letters were sent yet again yesterday and I want an explanation as to why my MTN account has not been updated since April? This is bad service at it's utmost best.
