CT Scan 12 June

I was diagnosed with bowel cancer in December 2017.  I had surgery, chemo etc - and so far so good.  

As part of the monitoring schedule I have to have CT scans every 6 months.  I had my last scan on the 12th June  and it's now the 30th August 2019 and I still haven't had a result - so we're at 2 and a half months - at this rate I'll be due my next scan before I get the results for my last one.  I've tried contact my consultants secretary - but it says you need some kind of ID code to get through???? I've emailed - but heard nothing.  Any ideas about what to do next???
