Sanlam life insurance service is very poor

I took a life cover and funeral plans almost 2 years ago and I got an email from one of the agents who wanted to confirm my details. I responded and asked her to confirm if she received my details but it’s been a month and there’s no response from her. I called Sanlam twice and I was on hold for over 20min. The third time I spoke to a consultant and I asked her to confirm my details. It is so disappointing that most of my details they have on the system are incorrect including my email address that they used to communicate with me (I don’t know how is this possible)???? I wonder what is the process when it comes to claims if the process of querying simple things is this bad. If you have a choice, please check with other companies first before taking a policy here. I want to cancel
