Bad print quality, NO response to my return request.

I ordered a Labelly label maker machine, and was very impressed and grateful for the timely delivery, and very excited to test it out! But to my great disappointment the machine's printing quality is too bad for me to use! Small text is not legible, and curved lines are blocky. Whether using an image or creating a design in their app - even when only using text - the printing looks bitmapped! I can't use this for my business, products, or even for personal use. Not only is the quality of the printing bad, but Labelly has not responded to any of my MANY requests since 30 December to return the machine and labels.
