Default listing removal - A failure

I am utterly disappointed, i was instructed to pay my account to sort out the default, since it has been 2 weeks since payment has been accepted, yet they refuse to remove the listing, and upon phoning i was first told it is only done on the 15th and 30th of every month, when i followed up, i was told it is only done once a month, the moment i remind the consultant about National Credit Act station that once full payment is made they have 7 days to submit the removal with the ITC, i get told the same line that we will escalate which i still haven't hear anything back from the first 3 promises to do so
