Absa not keeping promises

According to Absa I owed them an amount of an account which I did kot asked to be opened. 17 January 2019 Vanessa Crowe contacted me and said that everything is sorted and that I do not owe Absa any money. Today after 3 months I get a phone call from Vericred I asked for an email address to send her my correspondence with Absa she rudely dropped the call. So now I am asking why is this happening and I am sure that my name is now listed at credit bureaus. I am so sick and tired of absa and their empty promises and not helping me as a client
