Here is what happened:
I booked the original ticket during June. I flew the first segment in early July and was due to continue onwards to Australian on 29 July.
On 24 July I decided to fly to SYD instead of MEL so rang up Emirates in Switzerland (was there at the time) who re-issued the ticket accordingly.

Now EK is refusing to credit the promotion miles for the DXB-SYD segment because they're claiming the ticket was re-issued outside the promotion period (when in fact the flight that I took remained within the promotion period).

There is nothing in their terms and conditions that excludes such scenario so I am surprised at their cheap'ish interpretation of this.

What do you think?
