ABSA Bond Applications not handled correctly

ABSA ran a promotion for 10 000 off a bond transfer if you move your bond to them. As I am an ABSA client for years I thought this was great and app****. ABSA then selected a firm who was assigned to transfer my bond. This was 8 months ago. Since then they have told me I had to pay penalty fees because the documents where not submitted in time from the attorney. I managed to pay 25 000 cash as they requested with the hope of finalising my bond by June 2018. As a client I have done all that they asked yet now they are asking me to pay R 10000 additional for a shortfall again. I am getting married and the attorney said I cant until the house is transferred, when I told her its in September she assured me its fine as the house should be transferred by July. This is now August and after continuous frustrations and not being assisted I have asked ABSA to rather cancel the application. Now they are expecting me to pay R 5000 for them not doing their work
