Sanlam poor service

I tried to cancel my Sanlam investment as it has declined in value in the last 5 years and not once has the consultant contacted me once in the last 5 years as promised when taking out the investment. It took a few attempts to get through the right department and finally get the forms. I submitted the forms after a while after receiving it and they did not respond. When I queried it, they said that form had lapsed and I need to complete a new form . I signed the form and emailed it, requesting for someone to call me to explain if there’s an issue. I got an email again that the form if not complete and I must resubmit. I asked for someone to call me back and still no one has contacted me. It’s been weeks and I keep getting the automated emails. I’m sick of dealing with this company. The customer service is poor and so is the investment product and service.
