Brooks and Luyt worst customer service

I am utterly dissatisfied with the lack of concern and customer service including turn around time from the Wesbank Vehicle division under Brooks and Luyt. After receiving a formal offer to settle my account, I made the payment which is reflecting on the system dated 02/05/2024, i am still waiting for a Settlement Letter stating my account has been paid in full. Weekly i receive emails and messages asking for payment on the balance of the account yet when i eventually do have the luck of a leprechaun to get through i just get told.. Sorry mam you should receive your letter soon and yes i can see the payment. I want and need my official settlement letter urgently. All the mail boxes are full and no one replies to emails!! I was advised it can take up to 21 working days to obtain the letter.. Today is the 4th day of June 2024... Time is up!!!!
