Im unsure of what action to take...

Hey redditors!

Well I've basically run into a few problems, and was in hopes the community could give me more advice on which route of action I should take.

I placed an order last Thursday evening that I'm guessing was accepted, and then marked as shipped the following day on February 11th 00:56 Moscow time. It's now February 17th, and I have yet to see my order come in so I went ahead, and messaged the vendor about providing me tracking information on my order. They requested my order info.

I went into my Current Orders tab copied, and pasted the order details in the conversation between me, and the vendor.

I awoke next day (today) to a message saying we've looked into it, but were unable to find the order your speaking of, could you please provide a sale # as this is what we usually use to track down orders, but I had already provided the sale # in the previous message yet they're asking again? And at the end of the message was a new //please allow 24-48 hours for a response to your query on weekdays\

There is currently 7 days 22 hours left on the escrow hold, and I'm just wondering if I should wait a little longer to allow the vendor to redeem themselves? Or if I should just cut to the chase, and dispute the order.. as I don't pay extra money for Xpresspost to have my order lost/not shipped...

My first order with this vendor went smoothly, and I would've never expected this from a vendor of their reputation. Vendor has until tomorrow at this time before I name them... just hope everything is rectified as this is the only vendor that offered escrow for domestic H the rest require FE...

Quite frustrated, and unsure of where to go from here maybe you fine folks could provide me some advice?

Cheers!
