Inventory Bug

[sgtxd]

Three days ago, after I had bought desert eagles from Alie.Cat, I had also bought a Shelby GT500. After being banned for repeatedly testing car colors (admins thought I abused car menu), I came back three days later (present day), and end up seeing my inventory bugged. I have:
LOST: 5 P90's, 10 Desert Eagles
GAINED: 1 AWP, 1 Glock
Also, I have randomly gained an extra 40 slots in my inventory, making the max 80 from the original 40.
I am requesting a fix in my inventory and a revert back to what I had before, which was:
5 AK's
5 AWP's
5 P90's
10 Desert Eagles
I have worked very hard for the 10 Desert Eagles, and would not like to lose them just like that. Also, for evidence, you may ask Alie.Cat. Right after I bought her Desert Eagles, I bought her Shelby GT500. Therefore, I could not have lost the bought Desert Eagles. Also, after changing car colors a bit, I logged off to sleep, and found that I was banned the next day. Because of this, it was impossible for me to lose my Desert Eagles. Lastly, my Steam ID is:
STEAM_0:1:14461004
So, I kindly request a revert back to the old inventory. Thanks!
