8 months payment missing

<p>Igot my car financed with Std bank in April. I opted to pay for my installments for 8 months in advance, on the 10th of may i went to standard bank to pay for my installement. i called the call centre the same day to cancel my debit order and i was told the payment will take 3 days to reflect an to call back on Friday. I called back on Friday then i was told to call back on Monday, i called again on Monday now i was told my payment is missing to check if i used the correct information i verified the details with the agent correct bnking details and correct reference number. i was told to send through my proof of payment of which i have done. now im being told it will take 21 working days for them to try and trace for my payment and that my debit order will go through on the 31st of May!!! i have paid a lot of money and i dont have a provision for the ebit order why should i suffer for their system i used the correct details and i am not prepared to pay that debit order month end. I am feeling vey angry and dissapointed at Std bank.</p>
