Comcast is blocking emails from Constant Contact AND sending UNSUBSCRIBE requests without asking

As of some time yesterday Comcast has once again decided that I don't want to get emails from Constant Contact. I am the person responsible for sending all of the emails from our group using Constant Contact. This has to stop. I will resubscribe only to be unsubscribed by Comcast shortly thereafter. The emails in my Inbox keep getting sent to my spam folder - I have turned off the spam filter. I have made rules that all emails from Constant Contact be kept. When I attempted to contact Comcast I was put into an endless loop with a moronic robot that kept telling me my backup email address and asking me if I needed any other help. Finally, it sent me to a human (or said it would) and I was kicked out of the chat. Every time I attempted to find a way to contact Comcast I ended up with a picture of the VP telling me to contact someone else - my local franchisee or use snail mail to contact Comcast if they could not help me. Seems even the VP gets charged for every byte that gets sent to him. I wonder how many letters and penalties he received from overuse of data (oh, and your customers should be streaming everything and video conferencing and basically making Comcast more money than we will ever comprehend. If we, the consumer, seem to be catching on, another non-transparent policy pops up that costs us even more money.) But I transgress. At this time, this forum becomes my last hope of ever getting my emails. Can you tell how frustrating it is to deal with Comcast? To whoever is reading this, please don't take it personally as you already know Comcast doesn't care about its customers; I hate to think of how employees are treated.

All I want is to reclaim ownership of my emails and have the option of deciding what I want to keep and what I don't want to keep. Comcast is blocking important emails (to me anyway) and sending me all kinds of scams and bogus emails that a 5th grader could spot a mile away.

What do I have to do to get someone's attention at Comcast?
