After switching to Xfinity mobile, my phone goes straight to VM for incoming calls, unable to answer due to user busy msg etc

I started noticing shortly after I switched from Verizon to Xfinity, that my calls are going straight to voicemail… if I’m lucky enough to be staring at my phone the same time a call comes in, I was able to catch a screenshot that gave a user busy message under the number

pop up when an incoming call comes in, but I am unable to answer because as soon as I see the screen flash, jt disappears and does go straight to voicemail. 

A majority of the time I don’t get a missed call, I just get complaints that it goes straight to voicemail as though I’ve blocked them. 

I have gone to the Xfinity store, got many new SIM cards, did an astounding number of factory resets, alongside with network resets, did crazy key codes on my iPhone, went to the apple store, made sure my phone is not on do not disturb, airplane mode, the contacts are in my phone and not blocked, I have checked all of my settings- you name it, I’ve done it to get this fixed but to no avail. 

upon looking at the different questions and forums, I am glad to see I am not the only one experiencing this because a lot of people were confused and did not believe me …. But this honestly seems to be an Xfinity issue!

did anybody experience this same issue AND get a resolution????

I will leave and switch to a different carrier if this doesn’t get fixed because this is impacting my professional life as it makes me look like I’m unavailable and slacking on the job!

In the event of an emergency with my kids, what if no one is able to get a hold of me????

As someone who works in emergency and disaster services, this is a HUGE liability on Xfinity’s part IMO……
