Absa's appalling treatment towards customers

This is a follow up on my previous complaint ref c-***7, I received a email from Sam Shabangu (complaints management in the absa home loan department) saying that they r attending to my complaint and I should I not get feedback back I should call a number the gave me. I called that number today only to speak to Itumeleng who said she could not assist me, I then asked to speak to Sam who had sent me the email that refers me to them, she said she doesn't not know a person by that name and doesn't even have numbers for him. I then called the complaint telephone number a d got through to a gentleman by the name of Tumiso, who told me he will escalate the case and get someone to call me.

Within an hour or two Sam Shabangu called me and I asked if he was calling to because of my complaint and he said yes and went to tell me why he couldn't not work on the case and that he only found out today when he was informed about my complain that my matter was moved to another department..... Meaning if I had not called to complain about him no one would b attending to my issue and then I asked him who is to b held accountable for this lack of communication and distress on my side. He said no-one wants to take accountability and no one will, he told me he will refer the matter to someone else and cc me in the email, I then asked how will it take so that I know when to follow up. He said he does know. May I add that he was practically shouting and very rude. This man who is supposed to be in complaints management department hanged up the phone in my ear... Absa's employees really suck
