Ok, waaaay back in late spring / early summer last year, I bought a waterblock for a Zotac GTX 1070 mini. Specifically, a Bykski N-ST1070Mini-X gpu block. I found it by chance on aliexpress - and bought it on a whim, as I wasn't even sure I was going back into liquid cooling at that point. Anyhoo, it arrived after a couple of weeks and I did a test fit. It didn't fit. The edge of the block hits the fan header on the PCB and prevents it from sitting correctly. Now, I could have whipped out the dremel and cut out a chunk of the acrylic so the block would fit, and I might have done that if it wasn't for the fact that, when the mounting holes were lined up, it was obvious that the PCB would occlude two of the four ports on the block's manifold (technically still usable, but heavily limiting it's utility). So, I contacted the seller to initiate a return and embarked on a magical journey of protestations and excuses over the space of several weeks. Eventually, after the seller went silent, AliExpress finally stepped in and I sent the block back - at a cost of £20 - sending proof of postage and tracking. This was at the end of September. Again the seller dragged it out until the time elapsed and AliExpress stepped in again to process my refund. I was supposed to get the return shipping back too because I could clearly demonstrate that the seller's page specified my exact card as compatible. That didn't happen - I was £20 out of pocket - oh well, lesson learned. Then, today, a courier rang the bell and handed me a package stating the intended recipient never collected it from his local depot, in Guang Zhou Shi, China. So it was sent back to me, four months later!?!?! So, now I have a GPU block that doesn't quite fit the card I don't own any more. There's no real reason for this thread, I was just gobsmacked and felt compelled to share. That is all.
I had something strange like that once. I put a res up for sale on OCUK MM and a guy jumped in and said he wanted it. He took about four days to pay me, so I kinda figured he was messing me around. Any way, he paid and I sent it. Three months later it arrived back with me. I guess he didn't want it. I tried to contact him but he never replied so I just sold it again lol.
I bought a pair of headphones once from the gadget show in Birmingham NEC, the brand was fairly well known at the time but not your usual players in the audio game. After a fairly short while the headband snapped near one of the cups, I had a 12 months warranty and had used my common sense in registering it at the time so contacted the company via email. They asked me to cut the 3.5mm jack off the headphones and post it to their warehouse as to avoid the fraud of someone claiming issues for a free second pair. I did that and posted to the returns address provided to me, made sure I sent it recorded so I could tell it got there. Royal Mail tried a few times to deliver the item before it sat in the local delivery office for collection. I contacted the company a few times to no reply and eventually it came back to me. I then tried to ring them and when It got onto the topic of returns the phone line went dead... Very weird experience
