Diversified Collection Services review: rude, disrespectful and unprofessional customer service

I had a collector from this agency who handles my case, whose name is Kody Myers. I have to say that he is the rudest and the most disrespectful person I have ever dealt with. I know that I owe a debt and that I had to pay which I was willing and actually made a payment agreement with the agency. He wasn't very helpful and just kept repeating that they are a collection agency, blah, blah..duh I already know that. It takes them forever to process and update my account. I left a message for the supervisor but I haven't heard back. This experience just showed me that these people do not care about proper customer service but instead just taking your money and paying your debt. It would just be nice to have both, paying off the debt and at the same time getting good service. Is this too much to ask for. I do the same thing they do, but I do not treat my customer this way.
