Poorly and intentionally Designed that way Most Irritating to use Customer Service Ever

I have Xfinity cable, wifi and home scheck to see if an oecurity contracts with Xfinity for years.  My front door ring camera died.  My local Xfinity store sells replacement cameras.  The problem is you CAN'T call your local store to inquire if they have one in stock or not.  They don't give customers the store number.  It is NOT on their website or posted anywhere.  They won't even provide you with their store number when you show up at the store in person.  The regional customer service (800) number can't check if their local store has available stock or not.  The only way a customer can determine when they get stock in store is to drive to that store and inquire.  The store personnel just say "we're out of stock now".  They won't give me the store number so I can call and see if they've received stock yet.  So I a long time loyal customer in good standing has to repeatedly drive down to my local store and inquire.  The really sad part is Xfinity thinks this is good customer service.  No other type of store, i.e., grocery, furniture or auto part stores would ever think of forcing customers to be treated this way.  Why does Xfinity think this is a great way to treat customers.  It's horrible and I wish I would have never signed up with Xfinity knowing what I know now.
