STYLETHREAD -- LET'S TALK SHOP!

it usually takes a full cycle for credits to appear (I'm assuming you ut it on a credit card and not a debit card).

UPDATE

So I finally got a credit for the item not included in my order, but a month after the fact.  Meanwhile, I emailed customer service again (after a week of hearing nothing) and got two responses back.  One said that a credit had been made to my account (nothing else, no apology for the inconvenience).  The other was a very apologetic inquiry from a different cust. service rep.  I emailed the responsive rep with a copy of the original email and explained why I was disappointed in the curt response I originally got, etc.  I then get an email from the cust. service rep that originally emailed me apologizing for her curtness and saying she was going to send me "a little something" for my trouble.
    Three weeks later, and I haven't received anything.  What should I do?  I don't want to seem like someone trolling for free stuf, but the principle of the matter gets me.  She told me I would get something. 

Many companies take at least 1 billing cycle to credit.  They still should've been nicer over email though and (apparently) followed through with their "little something."
