Rudeness customer service

I received call from Lungile from ABSA using the *** number. At the time that i answered, she started talking and just before she could go any further i advised her to call me at 13:00. The person did not even ask me if i am able to talk, she asked what was the reason for me advising her to call me at 13:00? why did i pick up the call if i was not going to give her time to speak to me? i had to respond by saying "i responded because you called, and had to advise you on the time that i can or will be able to take calls on". The response from there was shocking "what did you not just ignored or hangup". Is this how you want us as your customers to do? rather ignore your calls? Im so confused by this. If i am available at 13:00, not everyone knows this, hence i answer to advise on the time that i available on.
