I agree with what you're saying. I also don't feel it's wrongful to contact Apple support and expect a reasonable answer -- not "we'll get back to you" to deter/ignore the situation. And... To me, it isn't unreasonable to request, have Apple offer an exchange for a Sport Loop or maybe even a Solo Loop -- although, I don't know how close the materials are between the Sport Band and Solo Loop. Are they required to? Not that I'm aware of. However, it would be a polite response.Unfortunately you most likely have a allergic reaction to one of the materials used in the band's manufacturing. I realistically don't see you getting anything out of this other than a free band made of another material. Unless this was a widespread problem Apple is probably under no obligation do do anything about it. People are allergic to things. Sometimes they don't know it until they are exposed to them. A similar thing happened when the S0 watch came out with the Milanese loop. People were showing sensitivity to the nickel content used in the bands alloy and it was reported in the forums and on tech sites. Nothing came of it and that band is still being sold today. Planter's doesn't get sued or compensate anyone every time someone discovers they have a peanut allergy. This is a similar situation. I'm sorry and I know it sucks, but its probably not worth the time and effort you're putting into it.
Anywho... Yes, I think, @BasicGreatGuy and a few others are being WAY too "American" (i.e. litigation-happy, etc) about this.
