So basically I purchased some parts through Shopping Express at the start of the year. Once they all arrived I wasn't confident enough doing the build completely by myself as it had been a few years, so I reached out to a well-reviewed local store to do the build for me.
I asked the builder to keep all the boxes incase I need to do an RMA on anything.
I get everything back and find he's not done an amazing job.
The motherboard mounting screws were all random types, so not the mounting screws included with the PC Case. I had to fit these and take apart elements of the build like the GPU to do it correctly. I found the PSU mounting bracket was installed backwards too.
I then found that the non-LGA1700 mounting kits, thermal paste and screwdriver that came with the Noctua box weren't there.
I had to RMA the PSU on the build as it was making a strange noise (not sure if related to his work) but on repacking the PSU box I noticed the included bag for cables was also missing.
I'm just wanting to sanity check myself but basically non-essential parts were returned to me as part of the build. I reached out to him to give me these parts back but he claimed he thought he'd given them back, couldn't find them and that they weren't required for my socket.
So all in all, he did an average job and pinched a few things that I didn't exactly need, but weren't his to take. Unfortunately I'd paid him before I had a chance to review everything. Is this common practice in the tech industry? There's not a lot I can do other than request he give them back, move on and leave him a bad review.
