Disgusting service

I phoned Wesbank to sort out my debit order for the 1st as I changed jobs and now I have collections phoning me and treating me like a common ********. I have changed my debit order and for the 1st time you are calling me for something like this..I have never complained that I got paid on the 25rd at my previous working place and got debited from you from the 23rd. I am totally disgusted with the service I received WHY ARE YOU TAKING A DOUBLE DEBIT ORDER FROM MY ACCOUNT IF I SAID I GET PAID ON THE LAST DAY OF THE MONTH NOW Why is it such a difficult situation to understand that this was not my fault that the debit order was not changed and that your call centre stuffed up here. I am seriously sadden by your treatment to me. Kindly note that you have taken a double debit order with two different reference numbers and I do not appreciate this. Your lady Renay was screaming and shouting at me when I was trying to explain to her that I had phoned and done an online change of my debit order and she screamed at me. Then yesterday I had the lady from collections phone me and I told her that payment will be done once I get paid which I did change the debit order. Then only to get a nasty shock now that Wesbank has debited my account twice. with two different reference numbers for the same amount. On phoning today I spoke to a lady who also spoke to me so rudely. IS this the way you deal with your customers if one debit order which hadn't gone through and which wasn't my fault either. Sort your processes out Wesbank I been banking with you guys for years and this is the first time I have received such treatment...Totally disgusted.....I will let everyone know about this service I received and will be withdrawing my account with you very soon.
