Straight Talk Wireless Straight Talk Great promise, but total disappointment Internet

I ordered Straight Talk SIM card and prepaid plan via the internet for use with the "bring your own phone" program, in my case an iPhone.
The package arrived, and the SIM card was not compatible. I looked back over th website and couldn't see where the option might have been to prevent the order from going through for the wrong SIM. Couldn't find, so called customer service. Biggest mistake ever.
Operators were clearly in another, faraway land - both geographically and metaphysically. Before I could even finish explaining my situation/complaint, the rep's script must've said "I am sorry , bbut we do not offer the refunds" becuase the whole experience abruptly devolved.Of course, I explained that I wasn't ASKING for a refund, but the screen had gone up. I asked to speak to a supervisor and was transferred to some one else who was clearly in the same room (the background conversation was the same). After another maddening few minutes on the phone explaining my concern (and being told whole talking that we do not offer the refunds), I straight up gave up on Straight talk.
The company looks so good in a comparison of cell carriers, so long as the comparison is conducted in the vacuum of space, and without regard to any customer service related issues. This company toll-free number should be used as a textbook case study as to why outsourcing is so very damaging to a company (I don't even know that ST is domestic company, though, so this protocol may be 'de rigeur'...and I'm just a stupid American), I was so willing and ready (but not able) to be an ST customer but ran away after my experience trying to speak with them.
Fortunately, i was able to sell the SIM card and plan on Craigslist, as well as pick up prepaid wireless from AT&T for slightly less money per month.
Caveat emptor, fer sure!!!
I did not purchase my ST SIM and plan through Walmart, so have nothing to offer in re: Walmart's role in ST.
