No help received

I have been trying for at least 2 weeks now to get the documents required in order to cancel my medical aid, but no one is sending me the docs. Now i have gone into december which means my months notice will now fall into the end of January. This is unacceptable, you cannot play with people's money like this. There is clearly a reason as to why i have to cancel. I have tried to do things the right way by requesting the docs so that i can get the docs in , in time for the 30 days notice period but the staff at liberty is not making this possible for me. I have phoned so many times but every one keeps telling me that they will send it and they dont. I eventually emailed liberty on their enquiries email requesting a manager to phone me to help me and no one has called. This bad service i have received will obviously stop me from coming back to liberty again and i of course will not advise any of my friends, family or clients to go to your medical aid. You are going to be messing with my credit at the bank and this is unacceptable. I WANT TO CANCEL
