XDS worst service ever !!

So i logged a dispute about two weeks ago at XDS as i have a prescribed account reflecting on my credit reports with all 4 main bureaus and XDS being one of them.I sent the disputes department an email with a full break down as to what the reason is for my dispute. So an agent by the name of David Maduna is assigned to assist me by investigating and resolving my dispute. Yesterday i receive the following;

Good day

Thank you for your request.

Please note that we are unable to log a dispute for the for the following Reason: The Foschini account is not reflecting on the consumer credit profile.

Note that this request is now closed on our side.

this is how people like David waste my time, because if he is even capable of reading he would have seen that my email stated it use to be a FOSHINI account and was bought by SSD_CDS the company that contacted me to collect this prescribed debt. Compuscan dealt with the exact same dispute and within 14 days it was resolved. My future depends on this report and David is really messing with my life. No one ever answers the phone at the XDS disputes department. WHAT TO DO????? I need a competent person to call me and we need this resolved. By that i mean, a proper investigation to be done and proper feedback to be given!

A very Frustrated woman !!!!
