Wrong name information in invoice since months

Since months I try to change the name information displayed on the invoice. It just displays my name and lacks the name of the association I created and run this account for. It is a self aid group of patients but where I place the name in my profile it keeps not showing up on the invoice "SHG ME/CFS, LongCovid, PostCovid, PostVac". I also changed my name and include my wives you is the director of the group. But also change is not reflected. 

I am afraid I have to cancel my subscription ans resubscribe or change the service provider completely.

I do not get rembursed by the organization as long as there is a wrong name  information on the invoice. 

Thanks for any advice how you were probably more successful than I am.
