Ackermans Collection agents has a bad attitude

Its the second time that a collection agent has called and she has a bad attitude, she has dropped the call in my ear twice.. She doesn't even have the decency to say Goodbye before she ends the call. You need to teach your agents to be courteous because they giving you a bad reputation. If she doesn't enjoy her job then she should find another one where she doesn't have to interact with your customers. Its unfortunate that i did not get her name. PLEASE TEACH YOUR AGENTS PHONE ETIQUETTE
