I've been trying to get duplicate C79's from the VAT Central Unit Microfilm Section for a couple of weeks now without any luck.

I've tried the following numbers:
I called HMRC twice and both times they said the only thing I can do is to keep trying to fax but I've been trying almost every day for the past two weeks and I still get the error. Does anyone have a workaround or an alternative fax number that is functional?
