Refund still not Paid back

So we decided to settle our Finance on the 25 May 2015 it took 3 days for the funds to reflect, on the 27 May 2015 Stannic confirmed the payment and proceeded to close the Account, then on the 1 June 2015 Stannic took off there premium for the Car I called and they said the Debit Order was already submitted but they will Log a request for a Refund, it's been 11 days already and every-time we call we get told different stories, the latest is that they do not have the Banking Details to refund, yesterday we provided all the information even though it is on there system and they took the premium on the 1st ... This is really unprofessional for a huge Company to give there clients the run around, <br> I want this Refund Sorted without any delays, I am tired of calling and doing your Security Check and then getting transferred to other Departments only to get told we need to Speak to a different Department...<br> <br> I am going to Email all the Directors of Standard Bank and tell them how pathetic there Call Centre Staff is
