Arrow Website said they could not generate unlock code?

I requested for a sim unlock code from and they claim that after about 24 hours of trying they could not generate an unlock code for me and sometimes "because of certain firmware versions" they cannot generate the unlock code Sounds weird and the firmware shouldnt matter, but anyways I'm not an Verizon customer so I cant get an unlock code from them so anyone had better luck with some other website?

Also I am aware that I need more then this to get it working on AT&T but I still need this as the first step.
