Double Gem Stash Tab

I accidentally bought a Gem Stash Tab that I already had
I forgot that I already had it and bought it again
I now have two of the same ones and I would like to ask you to eliminate one Gem Stash Tab
I don't know how to do it from the game, maybe support can do it
I don't want my points back, I don't want anything except eliminating this double tab
Please
