Worst Customer Service

This is one of the worst experiences I have ever had with customer service. My comcast email had been “blacklisted” and I called the customer service line for help. After about 40 minutes, I was able to talk to a real person. The woman told me she would escalate my ticket and one of her superiors would call me back because she was unable to help me. I got no call. I called back again and gave her my ticket number. He tried connected me with someone who could apparently help me but after 30 minutes on the phone with him he said he would send my ticket to his superior and they would call me back. It has now been 3 days and I have received no call, once again. I ended up changing my email on EVERY platform I had previously used my comcast email for. I am truly shocked by this experience and could not be more disappointed with the customer service I received.
