I believe ESN cloning is illegal, so that's likely a no-go as well.
You will either need them to let you exchange the phone for one that works where you reside, or buy a new one out of pocket. Did you buy the phone from ST or from a private party?
I recently purchased a Samsung Precedent from Straight Talk. I was under the impression that Straight Talk used Verizon towers but it appears this one is on Sprint. Sprint has no service in my area, is there any way I can make the phone run on Verizon by flashing it or anything?
I got the phone used to returning it is not an option.
