enter xbox live gold 6 month error

Yes it will, Xbox LIVE Gold subscriptions add up, so if you had 6 months left and entered a 12 month code, you would then have 18 months.

It tells me I have error 8C15009. Sorry their is a problem with Xbox Service try again latter. "Been trying for about 2 Weeks, Patience gone"

Cannot download from Xbox gold live. Cannot play games that require Xbox Gold Live, Ask me to buy Xbox gold live when I have a 12 Month paid subscription. Cannot enter manage membership. Cannot enter redeem code. Cannot enter Purchase history.

It will connect to Xbox live just not Xbox Gold.

To put it simply my Xbox 360 cannot use the 4 months of Xbox gold live I have in my account.

When I use a PC I can enter the account and all features and it shows I have 4 months of Xbox gold live to go.

Everything worked fine until a couple of weeks ago.

As I mentioned Xbox support cannot fix it.

Same problem keep getting the error message when trying to enter a 12 month prepaid gold live code.

same problem in entering 12 months Xbox Live Gold Online-Code from one website. We get error code Xbos1005. I am very frustrated and deceptive

So my regular subscription will just continue after the 6 months is up?

No. If you already had xbox live gold then when you add an xbox gamepass ultimate subscription (which includes Xbox live gold) it upgrades your existing Xbox live gold subscription to gamepass ultimate (hence why your gold subscription "disappeared")

So lets say for example before you added the gamepass ultimate subscription you had 6 months of xbox live gold left. When you added the 6 month gamepass code youd essentially now have 12 months of gamepass ultimate in this above example.
