THIS IS FOR THE COMCAST/ XFINITY IN CORINTH MS

My father-in-law passed away. While handling his affairs I had to shut off his xfinity as well as return the boxes. Well I went to both Corinth locations at 4pm. There was a sign on the door that read OPEN. Also the business hours were posted 9AM to 5PM. After seaeching the internet I found a post saying the Corinth stores have been shut down. I am still in possession of the boxes because I do not know his pin number to his account nor can o get it due to his passing. This whole situation is a mess, unclearly communicated to their customers. And if they charge me for these boxes, well, I'm guessing you can figure out what they can do with said charges!
CUSTOMER SERVICE MANAGEMENT SEVERELY NEEDED!
