Urgent referral

Hi I found a lump on my jawline. Went to GP and was referred to maxifacial clinic for urgent 2 week appointment. The 2 weeks is up this Wednesday. Received a letter today from ENT saying I have an appointment with them on 14/11/19. This means a month after I saw my GP

The lump has now grown so much in 2 weeks that is noticeable. (it's about 4 inches by 2 inches and has spread up my cheek) I can no longer use a spoon to eat with as my mouth won't open properly . Can't even eat a banana. 

I've told my GP and he said he'll try and bring the appointment forward.  Does anyone have any ideas what I can do to be seen sooner please?
