Refusing to change Home Loan debit order date

<p>I’m a platinum account holder with FNB whom have been promised excellent service, but my experience on most occasions have been the opposite. I started this process on the 12th of Des @ 3:55pm!!!</p> <p> </p> <p>I have been trying to change my debit order date of my Home Loan with FNB for two weeks and have just one brick wall after another. How can I be refused to change a debit order date? I have emailed my application and have been asked stupid questions even after providing all the necessary documentation, the last question was "Please provide the bond account number." Every time I need to wait another 2 days before I get a response, today its been another 3 days and still no response from FNB...</p> <p> </p> <p>I have also just spent 30min waiting to speak with a supervisor, to customer care consultant had to stand up and walk around the office form desk to desk to try and find a supervisor. Surly the best digital bank is capable of better service than this!!! </p> <p> </p> <p>There is not clear explanation as the why the debit order cannot be changed, and there are NO supervisors available to speak with.</p>
