WORSE SERVICE!!!

I changed my savings account to a Cheque account in November 2014, Absa did not switch over all of my debit orders and 1 of the debit orders is a personal loan I have with Absa, I contacted the call centre on the 23/01/2015 to check if all was in order and the lady advised me that there was 3 debit order that was not moved over the debit date is the 25th and she confirmed she could not move it over. I then asked her to move the deduction date to the 1st just so the debit will not be unpaid I went in to the Centurion branch on the 26/01/2015 and cancelled the debit orders and confirmed I will do an internet transfer which I did on the 26th and the 27th, I received a call last week that my loan is in arrears I was told that the payment was received in January and because the date was changed to the 1st February's premium is now due, If I was told that this is the impact a debit change of date have I would not have changed the date, if the debit order switch was completed like it needed to be I would not have has a problem in the first place. A manage was going to contact me and to date I am waiting for the call, I have been banking with ABSA for the last 13 years this is poor service
