Debit order gone wrong! !!

I havery been so overwhelmed with the excellent service I have been on contract with Telkom and being an ex employee with their customer service I expected better but I have experienced the pain clients experience. My debit order date is for the 25th of every month and on the invoice it clearly states that if the 25th falls over the weekend they will debit the next working day which never happened in my case they debited my on the 24th clearly there was no money as I get paid on the 25th I then called the call centre and asked them to redebit which I was advised it CAN'T be done I must make a manual payment which I did on monday after calling but yesterday to my surprise I was debited and today when I called to get the refund spoke to the agent by the Thandiwe who just advised me to do a reversal which I wanted to avoid and she even advised me that is the best option as the refund will take 14 working days wow guys having worked for the call centre I'm disappointed and with all the good things I have been posting on Facebook that I was just having the most amazing experience all that has been ruined. ......?
