Where are you from, dude? Over here in Argentina, it has been my experience that they don't have even close to the same standards that the U.S. has when it comes to business practice and professional courtesy (although, the U.S. is far from perfect, too). There are no strict, or even loose guidelines for hardly anything here, it's kind of a free-for-all, and you could expect to get the run around quite often, especially when handling paper work. So, If you had called to complain, they might have hung up on you, or said something like, "Sorry, about that. It happens.". They do not offer refunds here or store credit, in my experience, so complaining is virtually pointless. Mostly, you might wanna just bring it to their attention that there was a mistake, especially if you could have been hurt, so they try to pay closer attention, but no one really cares, and most employees don't take their job seriously, especially when working in an ice cream shop. It also depends on the individual you speak to about it, some people will show genuine concern, while others will shrug it off. Since all business in Argentina, at least in my personal experience in Buenos Aires, Palermo, and Lanus, are privately owned by families, or private companies, they will not take you seriously because it's not common for people to complain here about those kind of things, most people just won't buy from that shop anymore. Here, people are a lot more relaxed, and they don't believe in washing hands before handling food, as I have seen in the Carniceria and restaurants, and they charge whatever prices they want to, regardless of competition, because they can do whatever they want, and so can you, for the most part. Sorry, that was longer than I intended, but just though I'd throw some personal experience out there. Just make sure you watch out for those things, because there is no Better Business Bureau here.
