Poor Service

I have currently a study loan with Absa and need to renew it yearly. I went to Clanwilliam Branch in January 2021 to do the paperwork. Until now I am waiting for an answer. I made several calls to the Branch and also visit he branch. Each time I was told that they are still busy with the renewal. In the mean time I have to pay a full loan amount which is 3 times more than I would have paid. Absa Head Office is phoning me and tells me I had to sort it out with the Branch Manager. I am making the follow ups, no feedback from Absa. Now when I phoned the Branch in Clanwilliam, I was told that the Manger is busy or in a meeting and he will phone me back. But he is not phoning me at all. Absa your service is pathetic, after all this years, is this the service I am getting. Shame on you !!!!
