From bad to worse :(

After numerous telephonic conversations my bill from telkom stil has not been sorted out after i have sent them the correct "final invoice" that telkom has sorted out after 10 months of struggling to get the correct billing and now i am blacklisted as a direct result of nubebt's and telkom's negligence. This is not acceptable, ive never had debt of any kind or a bad credit record and now this because nobody is actually helping me just sending me emails always saying that im the one in the wrong :(
