Discovery bad service

I have had nothing but bad experiences with them. I cancelled my discovery and told them to keep my vitality. They cancelled both my medical aid as well as my vitality even though I have life cover with them as well. I have sent emails to fix this. Today I went a step further to phone them and went thtough all the voice promts. Eventually they transferred me to a line where an agent would have spoken to me. After several rings the line said extension not valid and cut me off. Do not waste your time trying to get anything out of them
