Horrible - Sizes are too big, and they don't exchange

Maidenform's bra was labeled the correct size, but when my wife compared them to another bra that they sent her you could see that it was an inch and a half shorter in length, and the cup size was smaller too so it did not fit. They said over the phone they could do an exchange, then when we paid $10 to ship it to them they said 5 weeks later that they do not do exchanges. They have no consistency in their bra sizes, and they have terrible customer service support.
