Connection issues on xbox one

I have seen alot of people writing about not connecting or finding other games to join and this has been going on for months, it’s now June 18th and nothing has been done about it, where I am from when you advertise a game to be multiplayer it should be multiplayer, you people at gearbox and 2k have had plenty of time to get this sorted, but no, you will concentrate on battleborn and ways of making money but if you do not get this sorted you will lose me and others as loyal gamers who trust your customer service, this is unacceptable and needs to be addressed, stop ignoring your customers and loyal gamers and explain why for months people can not connect to other games, I have wasted my money buying the same game for xbox one which I had on the 360 and cannot even play with friends, give us a explanation why this is?
