Their consultant sold me a policy, she **** and said my policy is how I wanted it until I decided to check on the Old Mutual App, That is where I realized she mislead me. I opened another Policy which is how I wanted it to be. I canceled the first one but still it debited on my Bank Account. So both debited. I called them regarding this and they told me that I will not get any refund because I canceled the Policy on my own
