Vodacom customer service very dissapointing

I've asked several times for Vodacom to rectify on my Transunion report that I dont owe them a cent since June. I've had zero response and action and I'm tired of chasing. My credit score is negatively affected as it does not reflect the truth. I've even sent confirmation of a settlement letter, still no action.

On top of that I still receive Betty Khosa's statements when I've been sending mails saying I'm the wrong recipient. I'm sure the account owner is wondering why she doesn't receive anything from Vodacom. Please please can you at least respond and also fix this mess.
