Oldmutual the best ******

I wonder what was i thinking trying to take an insurance with this company, my wife worned me and guess what? I tried to take a retirement policy with them, did the whole paperwork and after a week I realized that the debit date is wrong. I called in and sent emails to ask them to change it and they said it can't be changed and there and there i canceled the policy, sent letter via email and got the confirmation showing the cancelation. Now you why the debit order still going through? And the bank can't stop it and they don't want to return my money. ***?? you guys are ****** and I'm taking this matter to court and all social media platforms.
