Rogue Poison Questline Didn't work

Hi all,

Yesterday I finished my Poison Questline properly but I didn't get the skill at the end of it.

I already opened a ticket in-game and I'm still waiting for a response. What should I do? I completed the questline correctly as I always did.

*I'm a level 41 BE Rogue.

Thanks in advance.

You no longer need quest for it, just buy poisons from vendor

Ok. Thank you!
