Hey there @treysuttle
First thing first, Sonic Academy is just acting as a reseller here, it's a 3rd party sample pack, not one from S.A so for more details you should query the pack issuer, in this case CR2, you should find a read-me file in this pack with contact information, but anyway it's generally not possible to get a refund when it comes to digital audio downloads, that's the usual policy because it's not like a physical good that you can return to the manufacturer, you own the content upon download.
That said, CR2 makes high quality sample packs, I don't own this one but I bought a few packs from them and I'm very happy with the quality. The tail you're talking about is probably due to the genre, especially with drums & kicks loops, in Techno & even more Industrial Techno, there's a heavy rumble effect on the kicks & drums, that's a very specific distinction for this genre. Since there's construction kits in this pack, those loops are probably heavily processed and production ready.
To make them fir your needs, you can warp them or chop them depending of your DAW tools, use different loop points or isolate sounds and even use a gate effect and rework your own loops. IMO, it's always a good habit to make your own loops out of those packs, it can be very creative and you'll end up with something different than all people who bought the same pack and used it as it is. But again after listening to the demo and taking a look at the content description, I really think it's because of the genre, CR2 does great stuffs
Hope this helps
