[SPLIT LIP]

I have no idea if this is the right right place or not, but I'm kind of in a spot and need advice, so if it's wrong could a mod please move it?

I'm in a deal with someone fo an item and it's kind of not going well. It's been a week and a half since I contacted them, and I've yet to be sent an invoice for the item. I've sent a total of nine pms to them, and have only recieved four. The communication is very lax, and they don't seem to really mention the fact that it's taken nearly two weeks and I still haven't been invoiced. They send fairly short, hand-wavvy statements like "I'll get it done next time I'm out" or "I'll try this week." The price for the item isn't even that great, and the minimal communication has been kind of worried.

And there's been no explanation for it. The most explanation I got was a brief mention of weather, but they still post actively and I don't see why they never just explained to me "things are hectic, I'll try my best, but communication could be slow?"

Some advice would be greatly appeciated.
