AiT Loyalty Membership & Email

Asked if they could reduce to the size of the loyalty widget for better visibility on my mobile phone. They said it's not possible. I don't believe that at all. Anything in a website can have the size changed. They don't want to help me for unknown reasons.
Now insisting I get on the phone with them. Refusing to discuss over email. Very unprofessional. Now have to report them to Shopify and figure out how to remove the app that is fully imbedded in my website.
