Pathetic customer service and bank

Absa Vehicle Finance is the most pathetic department i have came across. For 5 years we have been paying on time and made a stupid mistake with our last two payments using the incorrect reference number now we are being treated like **** by their consultants and no one can give feedback about the money. We are trying to settle our account with them but are sent from one person to another. Kingsley in the accounts department went so far to have an attitude and ask whose problem is it if we used the wrong reference number and threw the phone down in my ear. Absa your staff and bank is pathetic and i will never make use of your services again. I am moving all my polivies as well that i have been paying for for over 13 years from your good for nothing bank.
