Ruby Rudeness

So i get a call from ackermans and at first this agent whom i don't know cause she didn't even introduce herself is thanking me for KEEPING my PROMISE that i made last month to actually start paying them off so they can stop harassing me. So after i ask her very politely why she's calling because the last person i talked to i've made an arrangement with of how much each payments going to be etc and what date i i'll be making payment,she suddenly changes her tone and becomes the rude illiterate she is because if she just listened like they never do this would never have happened but she upset me so much i dropped the phone in her ear, firstly it is not my ****** problem that they can't update their systems or that the staff are lazy i couldn't hear a thing she was saying because she was going on like a banshee!But that's what they do in call center,they want you to pay and they try to intimidate the money out of you i mean really i think these retail stores should rather train their personnel first before trying anything else and increasing our debt with their calls and ****ty agents cause it's because of them that you will lose greatly!
