double debit on my account

I have been double debited on my account I have been to the bank over 5 times and called the call centre on many occasions, My debit order has gone on the 29/05/2015 twice and I seem to be getting the run around all I have asked or been asking is for the debit order to be reversed which has become such a hassle.<br> ***<br> ***<br> ***<br> ***<br> <br> I have called in again this morning 04/06/2015 requesting feedback and was told that someone will get back to me as they are busy resolving me query. It has taken 5 days for one person to look into my account and see what the problem is, which I am still awaiting on a call not for an apology or what has happened just to know will the money be reversed.<br> <br> I been using my time,petrol and airtime which there has been no result.
