Unsatisfactory client service by Sanlam

I was at work when addressed by a consultant or advisor rather Miss Tabia and she advised me on an investment plan, I agreed to open an investment account with them at the interest rate of 10% but when I received documentation it was a funeral plan policy. I immediately notified her and told her that this is not the product I wanted and for her to cancel it because I am unhappy with her dishonesty. She explained that it is an investment plan with a funeral benefit but I insisted on cancellation. She sent me cancellation forms and advised me to email it to *** and I sent the email but it has been over 3 months sending multiple emails to Sanlam with no response. I tried registering an investment with them online and it did not even show that I have an investment account with them. I want to cancel the policy and a refund on my money because they are deducting it from my salary but they don’t have the courtesy to even provide effective service. It is definitely the worst customer service I have experienced.
