I understand your frustration and agree with you. I don't think you were being difficult or rude, it's probably them that misread and there was a misunderstanding. You have all the rights to not use their services from then on, but at this point, all you can do is wait for your things to arrive.

I use Crescent Shop and my things haven't arrived yet either, so I think pretty much everyone is still waiting for their order to arrive. I've never bought anything from mu-mo before, so I don't know if being slow like this is common or not. But there are many people buying the AT08 goods, so I'd guess they are very busy at the moment.
