Don't buy anything from WigSis. My story is essentially exactly like every other nightmare story recounted here--except I received a full refund because PayPal stepped in.
If you already have purchased something from them, and are experiencing problems getting a refund (which you definitely WILL), CONTACT YOUR BANK immediately (or PayPal, if you used that) with as much documentation as you can:
1) Screenshots of the advertised product and contrasting photos of what you actually received.
2) Screenshots of any written descriptions that are false
3) Screenshots of WigSis's return policy
4) Copies of any pertinent email exchanges with WigSis where you have asked for a refund and they are jerking you around.
I truly hope this helps at least one person, if not more.
