Who gave WesBank permission to change my Debit Order Date?

I received an SMS and then an email that I had requested a change to my Debit order date, I then received another set saying that it was a mistake... I then received another email stating that ON MY request the debit order date had been change to correspond with my salary date the 22 of each month (I am not paid on the 22nd). I sent an email querying this and was told to wait up to 5 working days for a reply, well its been 4 days now and I am tired of waiting, honestly is there only one person doing this? - I am sure with the finance charges we are paying WesBank could hire a small city. Something is seriously wrong with the system if this could happen!
