Forced onto Business Plus instead of the intended Business Starter plan

[Chelo19]

How can I get into the Business Starter plan when it's not even giving me the option?

I'm currently on free trial, but I need to be sure the billing plan is the correct one before setting up my services.

As you can see in the image I presented, I don't even get the option to get a cheaper plan.

Thanks for your support!
