Bad service

Good day, Please assist my complain is for both the ER24 and bestmed, last year August i fell and i had no one to take me to the hospital, i call in ER24, got to the hospital and was told that i had gastritis symptoms and the kept in the hospital for +-4 hours and gave me some medication. At tye point of the call i felf like i was loosing my breath and the only thing i could think of was an ambulance because it was late at night. 11 september 2020 i received a call to advise that i owe ER24 2500 for transportation that happened 12 months ago. Today i decided to call the dispute the amount beacuse the medical was supposed to settle the bill, and was told that bestmed declined it because "they feel it was inappropriate for me to request for ER because tge condition was not life threatening. The question is what was i supposed to do when i felt like i was dying and had no one to help? And secondly why am i paying for a medical aid if emergency are classified? Please help i am not going to pay because it was within my right to call as i was very sick, if it wasnt the case i would have slept at home and went to the doctor the following day. The might be a chance that ER 24 never submitted the claim to the medical aid.
