Sanlam poor service

I have been trying to get a correction of a Taxe directive that was allocated to the wrong tax number since November. wf_*** You call the service desk, send emails and nothing positive comes out of it. Everytime you speak to someone different who seems not to know who is supposed to assist you and they say they are going to get someone to contact you. I don't understand how service in the private sector can be this bad like i am dealing with the public sector
