Do you think I got scammed out of a Zhelm?

... like I said there were full and sometimes didnt even contact back, so i grew too desperate to get one. I should have waited in the FM for more well-known guilds.

Yes, sadly, that is the key. When you are desperate, the sellers (or scammers) have the advantage. It looks like you have learned that patience pays off. Hopefully other readers can learn from this, as well.

The big helm-selling guilds may not always be instantly reachable, but usually they have people you can PM, either here or on SW, to arrange the sale within a few days. I've had good results with two of them (in Khaini), and would never try to get a helm by spamming "B> Zhelm" in the FM or using a megaphone.

I hope it somehow works out for you, but I am afraid your mesos are gone. (I agree with those folks who pointed out some warning signs: Price changing, too cheap, unable to verify who people are, etc.)
