Hi my name is Sindisiwe Kubeka Vehicle license disc DG67TPGP is up for renewal and the car does not exist. It was financed with wesbank and the car got write off in 2018 however the car was never deregistered. After paying off wesbank they claimed to have couriered my log book with DSV of which when I made a follow up I was advised that the log book was lost from DSV. I made means to apply for a new log book to get the car deregistered and I was told the car shows it’s belong to Wesbank and Only them can apply for a new log book for me . I have been in contact with wesbank to get them to fix this problem of this none existent car that I am forced to pay for as it affects my other vehicle. Wesbank acc No: ***.
