"Call back waiting "

Requested 111 call back at 09:24 on Saturday 05/06 and was expected to receive call within 6 hours. Called them at 16:30 pm as not heard and condition worsening, to be told that I am in the queue but very busy. (Appreciated as I’m a full time care worker). It’s now 09:50 on the 06/06 and still no call back. I’m that ill that I can’t even stand without dizziness, my temperature is through the roof. I can’t eat or drink without intense pain. I can’t get my words out properly, it’s like I’ve had a good drink and I don’t drink. The worst part of it is I’m sole carer 24 hours a day to my autistic son.
