I need one more Xbox home switch Please I am in serious need

You're breaking Microsoft rules, at least it's not a family account.

You should always double check that you are purchasing items on your account.

As for getting another Xbox home switch, I highly doubt you will get another one Njal the Blue has already provided the link where you can
apply for another change.

Unfortunately nobody in support or on forums can add extra changes to Home Xbox. You can however apply for a one time only change explained at the bottom of this link https://support.xbox.com/en-GB/games/game-setup/my-home-xbox

Can I change my home Xbox console to a different console?

You can change which console is your home Xbox up to five times during a one-year period. This period works on a rolling basis, starting the moment you switch your home Xbox for the first time. If you reach your limit of home console switches for the year,
you’ll get a message letting you know the next available date you can change it.

Note Customer support cannot offer additional switches. If your console shows you’ve made five home Xbox switches for the year and you need assistance, select
Help when you see the message, Can’t make this your home Xbox. You may be eligible to receive an exception.

You can also get help with your home Xbox in Xbox Assist. Press the Xbox button to open the guide, select
System > Xbox Assist, choose My Xbox Assist >
Search, and then enter My Home Xbox.
