"Sinus Surgery"

My partner had surgery on his sinuses 2 weeks ago and needs a follow up appointment for removal of splints. They have ignored this, and just sent a letter for a 6 week appointment. After speaking to a very snooty receptionist who was very unhelpful we are no further to getting the splints removed. He needs them removing now, or asap since it has been 2 weeks and the NHS recommend no longer than 10 days, it is on his form as a required appointment. We are 'expecting' a call back, but highly doubt this will happen.
