Bad Service

I'm really dispointed about the service I'm getting from ABSA lately my bank. The explotation and incompetency from a big bank like this is really shocking.I feel harrassed especially with the matter in hand, I have being taken from pillar to post no one really to assist me with this matter.I'm not even sure what my next to go person who can assist me with this matter. I have being with ABSA bank more that 20years that how loyal I have being with them but at this present time, I even want to change banks if this how I'm going to get treated
