Stuck in Tirisfal Glades after faction change

Hi !

I just did a faction change to horde and picked Undead as my race. I am now stuck in Tirisfal glades with my only quest being ‘‘Call to Lordaeron’’ which asks me to speak to a Forsaken Dreadmage who isnt where the objective marker is. When i read the quest it told me to meet Caila Menethil who is in Brill but her dialogue options doesn’t advance the quest.

Please help !

I did a faction change and nothing happened.Blizz is a scam.
