Yahoo DSP acсount

Hi everyone!
I have a problem
Some years ago I advertised on what was then called Gemini which was the Yahoo, AOL etc ads platform. When I ended things with them, I still had some credit in my account with them.

I recently tried logging in with a view to advertise, only to discover that the company has changed hands and is now called Yahoo Advertising. My login is not recognised, when I click on their Contact Us option, I am invited to choose from:

1. Yahoo's Demand Side Platform.
2. Yahoo Properties (Sports, Finance etc)
3. Native Ads
4. Retail Media Network

I've contacted them many times on a couple of the above options but no-one has got back to me.

Does anyone know how to contact them to open an account? Or does anyone know any information about it?

Thanks in advance.

Try reaching out to Yahoo Advertising through their support email or social media channels, as they might be quicker to respond there

Try Yahoo's "Help" or social media for support.

Have you tried messaging them on Twitter or LinkedIn? Sometimes that gets a faster response!

No! It doesn't help... I don't understand why they have a contact form if they don't answer.
Or they answer selectively...
