Bad Customer Service from Call Centre Agent

I have an Udu loan and I made a payment arrangement with someone I spoke to on the 1st of June 2021. A lady by the name of Sizakele called me from +*** on the 10th of June 2016 at 07:12 and in a very rude manner tells me the person who called me a week before didn't before explain, she's demanding full payment and they are proceeding with section 29 unless I do a debit order. She doesn't even want to listen to me when I want to explain what the previous arrangement was with the person who called me a week before. And she's not giving me a chance to ask her questions on whatever she's saying. A very bad customer service from your call centre agent.
