Discovery Insure

We got a quote from LorenzoR@discovery that we accepted. When we did the paperwork I informed him that there were claims on our car. He never informed us that the installment will be more. Our debit order came off that was about R300 more and when I contact him he say I must speak to the help desk and the help desk kept on saying I need to speak to sales. Both sides kept on saying they will get back to me for a month but no one came back. End of February I made contact with Lorenzo again and he said he will help me. We went through the policy and he picked up there are differences but did not know why and he needed to send to IT to have a look. After half a day he got back to me and said that it was because of the claims and I start questioning why I was never informed. He kept on trying to speak around that till a point I ask to speak to his manager. He kept on saying he will help me but actually never did. I ask about 3 times to speak to his manager and to get the recordings and he did not want to put me through or help. At the end as I ask to speak to a manager again he just say okay he will get someone and put the phone down on me. It is more than a week now and still no one phoned me back. Absolute pathetic service from Lorenzo and Discovery Insure
