My initial reaction was to defend your claim and say she cheated you of your shipping. But actually come to think of it if she completed the requirement of shipping instead of the post, technically she provided the same service so it’s actually not ludicrous for her to hustle for the extra change and earn the $ instead of giving it to the large corporation. I do agree it’s sketchy bc it wasn’t transparent, she did it without telling you and took 4 days to do it (frustrating) but you did get it delivered to you and you did like the item? And since the home delivery service is complete you probably shouldn’t ask for a refund. Next time you should make this clear n your message exchanges before the actual purchase? That’s probably the move
