RPM MOTORSPORT LTD. review for Duplicate SKU Sync Master

I should have taken those reviews seriously, I usually like giving businesses a chance, but this app is doing exactly the opposite of what it is supposed to be doing. I am amazed, because its called Same SKU Sync, which means if 1 product has 3 same skue it will sync them together, this isnt doing this at all and when support responded to my issues they said "its because 3 products have the SAME SKU, this is why it will not SYNC" LMAO? are you seriously just taking our information to sell it abroad? I mean if your app says something and does the opposite, so what is your motive? Will be reporting this app to shopify to take action.
