Yet another disappointment from Absa

Last year Absa deducted my personal loan on the 23rd ( my payday is the 25th) I was told that there was a mandate on my account which I never requested. In saying that, my account looked bad as there was nothing in my account to deduct. I got a call from Absa asking why there weren't any funds in my account to deduct. So Absa's mistake became my problem. I asked for the mandate to be removed. I Was told that is was definitely removed. So today my personal loan was deducted before my paydate!!!!! I called the collections department and first I speak to Brent he says it has been removed (so the first time it was never removed) I ask him to please send me an email confirming that it has been removed, I should get it by 12 on the 24-03-2016.The time comes and goes. I call the collections department yet again and I speak to Thembeka. She says they had requested the letter from their team leaders and they were busy with it and I will receive it before the end of the day. I call again at 15:15 to be told that the team leader (Jarred) that was busy with my query had gone home already because it was long weekend. So I must wait until Tuesday for that letter. i am disgusted.
