new customer but no card to top up and in emergency.

Hi please can anyone help me

I have changed over to OVO and my supply was supposed to start yesterday. I have a traditional gas meter but OVO have not sent me a new card to top up and I’m about to run out of gas. I have tried to call and live chat too but keeps cutting me off before I even get through. 
my electricity meter is a smart meter and I already have activated my emergency credit I also am about to run out of this. 
I have tried logging into my account but it’s saying ‘oops something went wrong’ any help please? Or at least how to get through to a human. Thanks
