Xbox gremlins

Hi, I have an Xbox one s which was purchased for christmas. Everything worked fine on Christmas day. Boxing day, headphones stopped working. So I paired my controller from a 2 year old xbox. Sound worked fine for 12 days then no sound again. I tried three
other sets of headphones which I know work, to no avail. Contacted Microsoft help and we had the headphones working for 1 day. By this time, sick as a pig. So I connected my usb controller, worked fine but every now and then the xbox looses connection even
though its USB. I have to connect it to the 2 year old xbox to get it to work again. Then plug it back into the one s to use if again. What's happening?

XCOM 2 Promo codes

I received an xbox live message today with 2 codes for avatar props, the sectopod and the gremlin. I redeemed the first one, the sectopod, but the other code for the gremlin says it has already been used. I checked the avatar store and the sectopod prop
says "purchased" and the gremlin prop still wants me to pay for it. Thanks.

Thanks for the reply, I was thinking the same, so as I am an electrician I have done all the testing and it is constant supply.
