Pathetic service

I have to go in for a stent removal but cannot as discovery now wants me to pay in R5000.00 in order for me to have this operation at the hospital in which the stent was placed. I find this highly unacceptable as this is a follow up to a procedure that I had done last year at the same hospital. I have spent the last 4 days on the phone with different people from discovery and not one person can help me. For me to travel to a different hospital is unreasonable and would also mean that I would have to change specialist and have new scans done which I find unreasonable. Surely if this is a follow up to a previous operation I shouldn't have these issues being on a high plan. I dont pay discovery a little money every month. This is very pathetic service
