Banned from playing online

I have only had my Xbox and Halo 5 for less than a week but I am now banned from playing it online. Do you ban people because they are rubbish at the game - which I freely admit I am. Perhaps you should try harder to match people like me (level 9 - and I dont know quite how I got there!) with people who are level 140. Ridiculous.
I have been banned for 2 days now. That’s 2 out of the 6 days I have owned the Xbox and paid for Gold live.
Please get me back online.

There’s a Halo 5 ban thread that contains all the pertinent details.

And just to clarify, there are no bans regarding skill, it would be pretty ridiculous to ban people because of that.
