I would just like to add that I contacted them and they happily are going to send me my correct waterblocks as long as I send them back the incorrect ones, which to me is perfectly fine.

Reading through this thread I have come to a conclusion that most people who have problems with PPC are people who don't respect human fault.

Reading the OP's emails I did personally think he could have been a little more respectful and understanding of the whole situation even if he didn't want to. I understand some people find that hard to do but sometimes you just need to dig deep and realise what's best for the situation at hand. He might not believe that he should be nice because he's the customer and regardless of his attitude he will eventually get what he wants. My order was over $1600 so sure I was angry and frustrated when I realised they sent me the wrong block, but hey, sh*t happens right?

I approached PPC with the calm and respectful person I believe I am and look where it got me. They refunded the huge shipping overcharge which I didn't explicitly ask for, only hinted to them. They are also cross-shipping my proper blocks with the ones I need to ship back to them to ensure that I get them as soon I can.

I just think that when people approach merchants they should bare in mind that even if they are angry or emotional about the situation, conducting yourself in a calm and professional manner will get you much further than acting immature (I'm not saying the OP did) and being extremely rude about the situation.

Whether you think its right or wrong, act professionally, it's the best way.
