Terrible Service Impacting on ITC for Closed Account

On 7 November I approach Experian to remove a home loan debt with my name on my profile after giving them proof that I'm no longer linked to the debt/home loan. They told me STD Bank should provide them with the authorisation letter to remove the debt listed on my profile. I then approach STD Bank and explained to them what is required on 16 November and they gave me a service request no. ********** 872 and told me this matter will be resolved on 01 December. This matter was escalated twice at STD Bank and still they haven't resolve this matter. To make things worse they told me to approach Experian to resolve this matter.
