IT WHONT LET ME INSIDE THE MULTIPLAYER

for like the past 2-3 days xbox app wont let me make parties and call w my friend to play mc or even text them and i don't play games or talk to others to get banned so ik im not banned, are you having issues w parties too ontop of text or

Thats why I have the above tarrif dont use talk minutes at all. its always texts

on my situation i never sent a message to someone first. the person that probably sent the ban on me message me first and i replied. i been on xbox live for a long time ever since xbox went live and never been ban. what i dont understand is why ban someone
without investigating both sides instead of reading what i put and then make a decision. i never bullyed nobody and istay on the mic with my friends. for someone to be paying for xbox i dont understand why one person's report i get a ban. i didnt even get
what message i was ban for and why. all im asking for is if you investigating see why this happened and not take action. im 33 years old and dont bother nobody on live but people i know and if something was said it was because the other party not me. i do
not go texting people or inviting them to parties to talk. all im asking for is a fair judgment read what the other people sent.
