SRAM GX Eagle Groupset, 1x12, w/o crankset - HG 9/10/11s Freehub Compatible

Bikecomponents sent the wrong cassette for the rear wheel. We went back and forth a couple times then they said to send the sunrace cassette back and they would send the eagle cassette to me. Then they said they would have to charge almost 200 extra. You can clearly see in the product pic that it says it comes with the proper sram eagle cassette so not sure how them sending the wrong item would cost me an extra 200 to correct. Very disappointing, and I will never be ordering from them again. Cheating costumers is not the way to get return buyers in my opinion.
