SOWTECH Steam Espresso Machine Espresso Maker Cappuccino Latte Machine with Steam Milk Frother and Mug 3.5 Bar 4 Cup

How do I get my order number from this item which I purchased and has since been recalled?

Do you have to refill the water before you froth every time?

does this use a boiler or pump?

Is the water tank inside the unit made of stainless steel or aluminum? Can't tell if "stainless steel compact design" applies to the tank.
