Malware spam: "This is to inform that the transaction you made yesterday is declined." leads to Locky

This fake financial spam leads to Locky ransomware:

Subject:     Transaction declined
From:     Chandra Frye
Date:     Tuesday, 1 November 2016, 10:48

Dear [redacted],

This is to inform that the transaction you made yesterday is declined.

Please look through the attachment for the verification of the card details.

Best Regards,
Chandra Frye
The name of the sender will vary. Attached is a ZIP file (e.g. transaction-details_4688d047f.zip) containing a malicious VBS script (e.g. transaction_details_63EC6F26_PDF.vbs) which looks like this [pastebin]. That particular sample plus one other I received communicates with the URLs below, but you can be sure that there are many more examples:

Hybrid Analysis is inconclusive. If I get hold of the C2s or other download locations then I will post them here.

UPDATE
