First off there is no LIVE person for customer support. There is no phone number. Nothing.
Two: Why is Shopify Pay doing installments on a two week process instead of monthly? That is the most astatine thing I have ever heard of for a store. I should not have to use 5 million plugins to get monthly payments installed. I'm frustrated and irritated.
