ICPS non-service to me

ICPS, a service provider to Bonita's now wants me to postpone my knee op for a 2nd time. I just cannot anymore. Pain is excruciating and they say my diabetes is not controlled. Due to me having Rheumatoid Arthritis, it was discovered by Dr Hough who is a Specialust Physician/Endicrinologist/Diebetologist In Port Elizabeth after numerous blood tests that due to the RA, I have an auto immune disease in my pancreas which can be controlled, but due to the vast amounts of pain medication, my sugar is a little out of control. We have wasted hundreds on telephone/cellphone calls and speak to someone who appears not to be a Doctor and make decisions and does not refer for higher escalation. We have been promised for feedback but still no response. Bonita's have also promised call back which is not forthcoming then this affects my health as well with worrying about what is going to happen. Please can we have some positive feedback please.
