The same thing happened to me last year. Bought an Ultra Pro v4 and one week later they had a sale and refused to price adjust for me. Terrible customer service.
What is with this logic? You bought something, and a week later it went on sale. Happens all the time. That Wilson wouldn't offer you the sale price retroactively is not "terrible customer service." It's either poor planning on your part or just plain old bad luck.
Regardless, in your case, if you were so adamant about getting the sale price, you could have ordered a second racquet at the sale price and then returned the first one when it arrived. (Did you do it? My guess is probably not, otherwise you wouldn't be complaining).
