experian not fixing my credit listing.

On 24 July, after months and dozens of complaints vodacom finally promised to remove the "OFF TRACK HIGH IMPACT" bad listing from my credit profile within 7 days. It has now been twice as long and the bad listing is still on my profile. What does it take for a South African business to do the right thing? It seems to the rule for certain South African businesses to be as *******, *********, inefficient and *********** as possible. This is just pathetic and a disgrace.
