It sounds like the custom drysuit order you place got dropped by whatever salesperson you had spoken to, so BARE delivered what was ordered. While BARE isn't at fault, you would think that they would back their authorized dealer on the SNAFU and work with them to resolve the issue. It's not like it should be a big deal to take back a stock suit or trim a few inches off the legs and arms.
Anyway, it sounds like the issue is escalating, so if you can, call the credit card company and tell them that you are indispute over the purchase and would like to hold payment until it is resolved. They usually put a dispute down for 30 days and then either continue the payment at the end automaticly or you have to call them back and reverse the charges entirely at that time. I've only done it once, and I think that that is how the procedure went.
