Help me with my problem please.

It is against forum rules to name and shame other users, so please do refrain from doing so in the future. As for the issue with this user, it's best to block communications with them entirely and make sure you have no more affiliation with them. If they
continue said harassment, file a complaint through their profile.

Hello,

Please do not name and shame on the forums, there's no reason for that, and I'm not quite sure why phone support told you to post on this forum but they were incorrect in telling you to do so. No one can "hack" you on LIVE. The only way someone would be able
to get your information would be if you gave it to them. The most a user that gets your IP Address can do is boot you off of XBOX Live, that's about it. What you should do in a case like this is
file a complaint against the user, avoid the player,
block communications with them.

If you'd like this person to not have your IP anymore, you'll need to contact your internet service providers phone support and ask them to reset your IP Address. If your worried about your account at all, take a look at the
LIVE Security Checklist.

How to file a complaint:

1. Press the Guide button on your controller.
2. Select Friends, then go to the Players tab.
3. Select File Complaint. Then select File Complaint again on the next screen.
   

Select Text and Voice Communications.

Select Text Message / Voice Message / Voice Chat / In-Game Voice.

Select File Complaint.

How to avoid a player:

1. Press the Guide button.
2. Select Friends, then go to the Players tab. Select the player’s gamertag.
   
3. Select Submit Player Review.
4. Select Avoid This Player
5. Select why you want to avoid the player: Communication, Game Behavior, or Player Skill.
   
6. Select the specific reason why you want to avoid the player.
   
   

How to block communications (only works if messages were received from other players):

From the Xbox Dashboard, open a message from the player, and then select Block Communications. The player will not be able to send you any messages unless you send them one first.

I was previously using Internet Connection Sharing and it wasn't working, so i bridged my Wireless and Lan adapters, yes i did select both adapters and chose bridge. Which one is the best option? Any ideas?

This is happening to many people worldwide right now, unfortunately. I'm sorry you're experiencing this. This is a very common problem right now and it's a lot to do with services being overwhelmed at the moment. Due to worldly events, and many more people
being home right now than usual, and trying to play Xbox at the same time, the servers and services simply were not meant to handle this large of numbers at once. YouTube and Netflix and many other applications have also been overwhelmed in the past couple
of weeks and have had issues, and have had to lower bandwidth to try to keep services running. Please understand that this is the issue, and they are trying to work on it, but are struggling to keep up with demand. All Xbox services are overwhelmed right now
and this is a known issue with games not working, servers being down, downloads not completing, etc. Everything is affected. They have said they are trying to fix the issues and keep services running during these times, but just know that it is issues on Xbox's
end, it's not your Xbox. It's affecting everyone. Keep trying, that's all we can really do. If it does not work, you might simply have to wait this out a little longer and once work places and schools etc are open again, and lockdowns are lifted worldwide,
services will feel the relief and all systems will run normally again.
