Last year I ordered a kigurumi from and when they sent it, they had forgotten to include the hands and feet with it. I mentioned this to them and they said that they forgot them and would would send them, but they didn't do so. I messaged them again several months, and they said they would send them ASAP.

I was very polite about it but clearly that doesn't work because I still didn't get them. This all happened over a year ago ago. I messaged them a few months ago as well, but didn't get a response.

I'm at a loss of what to do. I'm very happy about what I did get, but I feel ripped off that I paid for the whole thing and still didn't get the rest over a year later. So I'm not sure what I should be doing at this point.
