Terrible service

Terrible company. I wrongly sign up for one of their offices spaces, and never step foot there or used the place. Multiple occassions people went to the place asking for me, they said the company doesn't exist there. Now 6 months later, they are sending me Invoices, Invoices for what? What exactly am I paying for, when I wasn't using the place, and you told everyone my company never had a space there
