I think you got a bad representative. I’ve been using Comcast for around 7 years, and they almost always hook me up with a new deal when the old one ends. I’ve only had one bad experience with their customer service in all these years. Try calling back and speaking with a different representative.
It's ironic that I posted a comment about AT&T having great customer service and then last week I spoke to a rude customer service rep at AT&T. I guess there's a bad one in every bunch. I don't know if I mentioned this ,but I found a downside to bundling all your services with AT&T. My service was interrupted for about 7 hours last week until I went to a payment center and made a payment. Anyway, I found out that if you get interrupted there's a $30 reconnection fee for EACH product. So if you have phone, internet and TV with them, that's a total of $90 in fees. That almost doubles your bill if you are unlucky enough to come up short. I wonder if Comcast has a reconnection fee for each product or one flat reconnection fee.
I also hate comcast for the fact that they don't really value their current customers. As others have mentioned, you can usually call back and get a "deal" if you say you plan on switching companies. However, they usually end up raising your rates later on hoping that you won't notice. The "deal" is also never as good as what the new customers get. My bf was considering going to comcast to get faster Internet because it wasn't that much more on the TV. I told him he could try it for a few months but to plan on getting rid of it as soon as the deal was over.
I agree with you that the way you were treated was totally unprofessional. Comcast more than likely will follow up with numerous phone calls and snail mail to try to get your business. This costly process could have been avoided had they simply said something like let me refer you to a supervisor or as you said "call us back if you change your mind".
I worked at a call center for a cable service once. I will be honest, the majority of people who work there are youngsters who just need a pay check and dont really care about the quality of customer service they are providing. Its usually a college student or someone looking for a summer job, why would they care about how they treat the clients if they know in a few months they are out of there and that position wont even go on their resume? With that being said I think they should screen and train their employees better and yes, she should not have said "OK Bye" and just hung up. She could have had a complaint put up against her with a manager that would have probably caused her a couple of days out of work or maybe even employment termination. I currently have comcast and Have had many issues with their equipment. They keep sending "new" equipment (cable boxes, routers, etc) to fix the issues and it never does anything but waste my time. I finally had a technician come out to my home and he had to re wire I dont know how many things because apparently the previous person who lived in my home had illegal cable and rigged the system which in turn didn't allow me to get any service.
