I had problems with my sons documents. They were scanned to the wrong application and then sent back to me.
I had to call everyday. Progress team cannot link the documents. But customer care management team can email head office and expedite the progress and get them to link / scan documents. And if after 48 hours of them contacting the head office they can chase again.
Keep onto customer care management team. They can actually do something where as progress can only put notes on the files.
