Thank you both! I appreciate you taking the time to reply.
For the benefit of others, I have tried to call and the only solution was to resubmit the application with the amended dates, then to call in again and let them know. They will then cancel the previous application in the system.
It was too much work as I was not in the country during that period hence. Hopefully this piece of information will be helpful to others.
Kudos to this helpful community!
