Xb10 availability

Hey I'm on there 2gig service I have a 10gig nic card they sent me a xb8 which apparently has inherent compatibility problems with actually going over 1 gig. Not to go total geek but basically it forced nic to negotiate to 1gig until it gets a full cold reboot every time I try to actually use it for any real purpose like downloading massive files. I talked to support they promised me an xb10 and I would have it in 2 days that didn't happen so I got ahold of them again someone new said I was misled and they had 1 at the store for me I just needed to go pick it up. Guess what nope they didn't have one either and was told by the store employees that only business plans could get them. So basically, lied to twice and one cost me time and gas going to a store just to have them tell me that nobody ever called them to verify they had one and that I wouldn't be getting one until probably next year. Unlucky for them fiber will be here by then and I'll be moving on to bigger and better things. So good job for losing more customers xfinity over lying you should get sued. You offered multi gig service with a modem that you knew from the get go couldn't hack the speed increase but you sold it anyway.
