Vehicle and Asset Finance

I recently got vehicle finance through standard bank. The sales person I was dealing with had advised that they had set my debit order for the 1st May 2016. On the 3rd May 2016 I received a call stating that my account is now in arrears as the amount due has not been paid. I then explained to the consultant that a debit order was supposed to have been set up and they advised that they could not see a debit request loaded (someone at the bank not doing their job) and they would load the debit order and debit the required amount on that day. I called a few hours later and they ensured me that the debit order had been requested and the payment would be made. On the 4th May I received an sms stating that my account has not been paid and I am in arrears. I then called the vehicle and asset department again, spoke to a NEW person and they advised that the debit order has been set and they would send through another request. This entire time they had been giving me the amount for the correct debit (this is an important fact). Then we get to the 4th still no debit order has been made, I then called AGAIN and spoke to e new person AGAIN and they advised me that the debit order was set to go off on the 4th and they would ALSO put in an additional request again for the CORRECT amount. Then we get to the 5th May, STILL the amount has NOT been debited. Call vehicle and asset finance again and they advised the request has been sent, bla bla bla, same story, they will put in a request for the same amount (correct amount), oh and they told me they would add in a note to state that I have made contact and that an arrangement has been made (nevermind the fact that the funds were available for debit and NONE of this was my fault)!! Anyway evening of the 5th debit order finally goes off for THE WRONG AMOUNT!!! more than R2000 less than was SUPPOSED to be debited!!!!! Called again... they have now apparently set the debit order for the outstanding amount and I have to wait till MONDAY 9th May to see if they actually got this right this time!!! They advised me to call customer care, so I did, and I was sent BACK to vehicle and asset finance!!!!!! Nobody could tell me WHY or WHO did not load the debit order correctly... or why this has happened! You cant get through to customer service for this issue. No support, just **** service as usual!
