Cricket Wireless Customer Service Email

Does anyone have an email address to Cricket's customer service? I bought a phone from the online store, but I ended up returning it. After a month of processing the return, just found out they won't take it back because there's "physical or liquid damage..."

It definitely wasn't damaged when I sent it back. I remember reading an old post saying it would be worth a shot to email them, but I am having trouble finding the email address.
