Query: Speed bag replacement bladder

The bladder was mailed and I received it very fast. The price was right but, the bag does not hold air long. It has a very slow leak and I need to add air every two days. When I pulled the bladder out of the envelope I noticed that where it was folded the coating was peeling off. If it did not leak air I could have rated it higher. If it's possible to get an exchange it would be appreciated.
