Undue debit order! Consultants not being able to help me

So, I wake up this morning with a debit order message on my phone and I called standard bank to reverse the money. I have literally been on the phone for 18 minutes, spoken to 7 consultants each one claiming they can't help me since I'm calling the "wrong" department, mind you, I was being transferred by them and at some stage they ended up transferring me to one of the department that I already spoke to!!! My airtime is finished and my money is still not in my bank account, basically my issue is still not resolved!!! One told me I should call the number on the sms, but that's the number I called from the very beginning
