Unhelpful, rude, arrogant

Firstly I went to oldmutual branch in kerk street wanting to cancel the life cover and retirement annuity that I have with them only to be told that I need to bring a copy of a bank st3as well as my ID, told the lady that I have it on the phone and she told me I must print it. I then asked her to give a phone number where I can call and cancel and she gave me a WhatsApp number ***which is not helpful at all, she also gave a customer care number ***. I then called the customer care number waited for +- 14 minutes just to be disrespected by Tyrone the agent on the phone, shouting at me like I'm his kid or something even after I advised him not to shout at me he continued to be rude an unhelpful. I requested to speak to his team leader and he refused. I want this life cover and retirement annuity cancelled. This is one of the reasons I want this policies cancelled, I was so irritated that I hang up the phone. I want a written apology from him, his manager as well as their regional manager.
