Seabourne Express Nightmare!

I have been dealing with Seabourne Express, regarding an Xbox Series S that had to be sent to Microsoft for a repair order. It has been almost a month, and no one can give me any updates as to what is happening with my order. Martha, the lady apparantly standing in for Keneilwe, thought it was rather funny and started laughing on the other side of the phone, as I was trying to explain to her the situation. William, the person you are supposed to call to escalate these orders, is never available to take these calls, so nothing ever gets done. I think the audacity of an employee to laugh at you on the other side of the phone, is a direct representation of how clients are obviously treated by Seabourne Express. I think Microsoft need to perhaps look into sourcing a different Courier to handle there repair orders, as it seems Seabourne are unfit for the Job.
