Early upgrade issues

So im more than over 50% of paying off my phone. 

Ive NEVER missed or been late paying an xfinity mobile bill nor my comcast internet bill and ive been a loyal customer for over a year.

Put over $2.3k into xfinity/comcast and i cant get what i was told.

Im 100% eligible for an early upgrade so i go into stores JUST for them to tell me i cant upgrade.

1. The xfinity agent had me to call xfinity (Whyam  i calling xfintiy in the xfinity store???)

2. The agent was really careless and lazy.

Long story short, i was told they was getting an error in the system and that they was going to refresh everything and if i go to a different store everything should be fine and that i wouldnt have any issues.

So i drive another 30 minutes to a different store just for them to tell me theyre all out of iphone 11s (Why dont any of the xfinity mobile stores have actual phone numbers???)

I ended up driving BACK to the first store, this time a different agent is taking care of me...

The same error popped up... with no explainantion from the store agent or the agent on the phone...

so i said i dont want the early upgrade anymore.. just give me the iphone11 on a new line and they told me it wouldnt allowed them. And for the third time i walked out a xfintiy mobile store without a phone......

I was told my "case" supposedly is going to be solved by Thurday (48 to 72 hours)

I am going to lose my marbles if i cant get my phone after looking forward to upgrading for a whole two months. It just unfair how the workers dont know anything, how im completely eligible for the early upgrade and i cant get it.
