Ridiculous service/Fraud

I've had an @Home account for nearly two years now and never had any trouble or missed any payment. This month when I received my clearscore report it stated that there is another account ( a Due South account) Under my Id number. I contacted Due South last week Tuesday and the lady whom I spoke to confirmed that there is another person's account which appears under my ID. She promised to send it on to get investigated. Wednesday I phoned again to find out what is going in regarding this investigation, and the Carmelita helped me and she told me that no investigation has been logged. She then sent an email and CC'd me in it to see that this problem get sorted out, but up to today, one week later I still haven't received any feedback regarding this and this guy's account is still reflecting on my clearscore, which means that it is still under my ID.

This is impossible as a female ID can not be used for a male (Carmelita confirmed that is was a male named IJ van der Vyver) and second of all he had his Due South account long before I even opened my @Home account.

I am SUPER upset about this as this issue is influencing my clearscore terrible.
