I'm not on that server, but this advice may be of use to you. It's not that rare a drop for an adept, so you should be able to get it. Judging by your name you are FP based. Besides checking the broker, are you checking the black market broker?
Now, prices for this can be high, over a gold. Black market, that's much worse w/ the high commission fee.
Try this - go into the commons when it is at its most crowded time and /auction something like "summoner needs to buy adept 1 Tell. Rct. I have 48 silver - could someone pls sell me one?" The basic idea is to personalize the plea - you really need the pet upgrade, you have money for it - you're trying to tell someone please just sell it to me now and get it out of your hair - and don't be greedy and try to get more for it later w/ the broker. Believe it or not this sometimes works.
If it doesn't you may want to take the griff to Nek and do the same there. If that doesn't work try to team w/ a very high lvl person and blitz through nek to the bell to TS - do the same - and then Antonica. As long as you can make yourself sound like a nice and deserving gamer to someone w/ the spell, you can often beat the high broker prices this way. (or you get lucky and find someone who hates sitting in his room selling). GL!
