Query: a refund would be a great starter. If I HADNT purchased a light box ...

In ALL the diamond paintings I have done, this one by far has been the MOST frustrating..... I believe the manufacturer of this particular canvas should DO RIGHT by ALL those who have purchased this item.... For example, a refund would be a great starter. If I HADNT purchased a light box and received today, I would have thrown it out.... The dark colors/numbers are ridiculous to figure out what is what.... PLEASE do something about this in further productions of the dark colors, symbols etc!!! NOT a happy customer!!!
