Dear Comcast folks, Due to connectivity issues with residential service, and the fact that I work from home almost 100% of the time, logging into a VPN, I setup a trial for Comcast business class, having been told by the salespeople that this may very well solve the issues. I need 100% reliable service. This did not solve the issues. In fact, the recurring issue was ultimately determined by technicians to be caused by a nearby customer's line interference. All the while, I was still paying for my residential service. Due to my disappointment with the lack of resolution to the quality of the service, I cancelled and returned the modem long ago. I keep getting billed for the trial period as well as the following month now. What's up? Why should I pay for a defective product that is not what was promised to me? I have had several phone conversations with customer service and apparently to no avail. I have been a Comcast customer for years and am quite angry at this moment, looking at a bill for 387.60 for service. PLease have someon call me at 224-406-3773 or 847-246-1596.
