Cannot pay fororder

After completing my order and submiting I get this

I don’t use Norton, I use Malwarebytes.
What do I do now?

I was not able to pay with my credit card, I kept getting that message.
Maybe BlueRobotics has been hacked.
I was able to pay with Paypal.
It was frustrating not being able to contact BlueRobotics for help which is why I posted here.
