Google Home & Yeelights

Good Afternoon, I am trying to link my Yeelights to my Google Home, I have some how registered 2 MI accounts, 1 in my email & 1 in my phone number. I am wanting to delete both & start off new. I can not find how to do this.

I also want to then sync them with GH but the link never goes thru & I have it set to Singapore.

Am I doing the right thing in resetting the globe & starting off with a new MI account.

I have just gone from adsl Broadband to NBN.

Please Help.

Thank You
