customer service consultant dropped a call on me

Good Day,<br> <br> I have a problem, i had an account with homechoice which was handed over to Nimble group where i settled the account last month and i requested that they provide me with a paid up letter and communicate my settlement with homechoice so that my name could be updated on ITC. Nimble only got back to me with the necessary but the issue is i called Homechoice yesteday the 30/03/16 to find out if my account appears to be settled on their side where i spoke to a laday named Babalwa at about 4pm she dropped the call on me as i was frastratingly addressing my problem to her, i called back again to report her to the supervisor and the agent who answered the call put me on hold for so long and refered the call to a gentleman named Abdull who refused to give me his surname for securty purposes he said. He was very rude telling me that he is a senior agent and supervisors are in a meeting i advised him to please get them to call me as soon as they are available but they havent till now. My worry is Homechoice is a big company and they need to train their call center agents to learn how to speak to clients and not drop calls on them, i am really angry as i used my airtime to call them
