When you request for GCMS notes make sure you are using a reliable service or else you will keep waiting for months to get your GCMS notes. Check the other PR forums and GET GCMS is what most people use. There are numerous GCMS websites run by fly by night operators to make a quick buck and offer cheap prices. It's a race to the bottom.
After having used GET GCMS, GCMS Online, and Buddy, all suggested here, I can tell you GET GCMS is much better. Its just more professional, IMO.
At the end, its your info, your application and your money!
All the best!
