Quality of Shirt Prints

So for my tshirts, I went with a supplier with a 9.6 star rating - UNDERGROUND THREADS - By NEXT LEVEL. A friend bought one, said they looked great, threw it in the WASH, followed the tshirt instructions, cold water, tshirt inside out to protect the graphic - hung to dry.

It was its first wash, and when it came out, pieces of the graphic were cracking / falling off.

It currently looks like it's a decade old.

I know I can get a refund or replacement for my friend, but my biggest concern is this happening to another customer, and how do I even discern what other supplier to go with when a 9.6 out of 10 is this poor in quality?
