"Refused to treat me"

I had a wisdom tooth removed 5 days ago , and have developed an abscess with puss , I phoned my dentist who was fully booked they advised I phone my gp they were also fully booked and told me to ring 111 . So I rang 111 was on the phone 30 minutes they give me an appointment at the Washington walk in centre . I arrived for my appointment in good time to be told there was a 45 minuets delay , then I was called nearly an hour later to be told off the emergency care practitioner the can’t see me and to go back to the dental hospital it’s the dentist problem. Even thought I was sent there off 111 operator. The time is now 5.45 I have puss ouzing into my mouth I’m swollen and can’t open my mouth much to eat at all and I’m in really bad pain , dentist is closed and gp surgery full . All I need is antibiotics and i was turned away what is the point of 111 . Also my discharge note from the dental hospital is to my gp not my dentist. poor service .
