Requested settlement letter not received for ITC despute

I had closed Vodacom account in March 2018 and in early 7th July 2018 I requested Vodacom to update my ITC status to “closed” as the account still reflects as “open”. The account was updated on the 15 July 2018 but it was still updated to “open”. This is affecting my overall credit status at Credit Bureaus.

I then request settlement letter till thus far I never received anything from Vodacom legal department, I recently called more than 2 times to Vodacom and I was promised the letter within 48 hours and days has passed and no letter is send to me. It is very unfair and disappointed as turnaround times are not taken serious and I am taken for granted.

I need this letter to serve as a proof that the account is really closed. Exprerian, Transunion, CompuScan and XDS are also requesting it to log a DISPUTE to update this account to “closed”.
