still no response on hospital insurance

its been a week since I sent my first complaint and I haven't received any response from edcon,i have called them since last week Thursday to check how far they are with my complaints and they didn't help me. they kept lying to me that they will call me after 48 hours and I haven't received a call,i want to close my edcon account. I don't want this account ever in my life and they Edcon are *****, *********** and don't care about customer complaint. I called them asking to talk to their account manager they gave me wrong numbers and blatantly refused to take the call to him. I have contacted Speak Out to handle this matter as im not being helped,im back at where I started. I really want to close this account what do I have to do to get this fixed,im frustrated and I have never in my life been treated to horrible like edcon is treating me. i hate edcon i want to close my account and i never in my life want to use edcon,i want them to fix this problem and close this account. i called them on this numbers: ***, ***,***,***,***,***,***. What else should i do to close this account please tell me what else i have been calling & NO HELP
