No one is going to call you, but...
I've asked a Comcast employee to help you. You should expect a reply in this thread.
How do I get my number back? It’s my property. The last rep transferred me to ‘legal response team’ to get the number back. He transferred my call to a GD fax machine! Why is Comcast customer service so god awful?
If you threaten legal action the customer service reps can't help you any longer. Instead, you'll end up dealing with Comcast's legal department which won't be helpful at all. I understand you're frustrated, but you might want to dial it back on the legal threats so you can get this resolved ASAP.
In my experience, porting numbers usually goes smoothly. When the process fails, it seems like it takes a long time to resolve. Did they give you any explanation?
Trying to activate service with XM was the worst experience I have ever had as a customer. 3 days. 8 hours on the phone. No response on the forums. No help from chat. Rude agents. No call backs from the mysterious 'tier 2.' Seriously, what kind of customer service is this, you cannot call Tier 2 directly and they never call back?
And to top it all off, they lost my freaking mobile number!
Never use Xfinity mobile, it is not worth saving $20 a month over Verizon Wireless.
