Rude customer service

First I want to say Ladonna or Ladonni was great. However I was transferred to another agent by Representative Ashley. That Representative did not give her name, had me on hold for 30 minutes and then she hung up on me. She could not answer basic account questions and did not want to look into my billing issue. I have never called a company and spoke to someone so long that was unwilling to do their job. I was about to ask to be transferred to another agent when she hung up on me.
