Consultant from Presumably ABSA bank loans department called then hung up when i asked questions

I was contacted by an individual from the ABSA bank call center. The gentleman that contacted me spoke very slowly articulating every vowel in every sentence he was using. I asked the gentleman to speed up as I don't have the time right and he advised that he cannot do that. The gentleman did not state his name or the reason for his call however he called me from a ********** number. I assume he called me with regards to my now up to date ABSA personal loan. The gentleman hung up the call/terminated the call without my consent, the gentleman came across as sarcastic and when I asked him if he was trying to be funny with the impromptu manner in which he spoke to me he hung up the call immediately.

I do not know why I was called from this ABSA business unit, I do not know the nature of his call and I do not know what his intention was. I do know that I'm not sure if this is how ABSA conducts themselves telephonically .
