Cancel my IFA policy and and reverse my money

I'm writing to you IFA clientele because i have a complain. July I joined IFA and during the process I was asked which day of the month would I like the premium fees to be debited ? I told the lady that on the 22nd would be the perfect day and she asked on which month I told her August would be alright since I already had plans for the month of July but on that very same month my money was debited and I was a angry as I am right now, I went to the bank and reversed the money as it was supposed to be debited on the month of august and I think on the 24 of July I received a call from a white lady who gave me an attitude and asked why did reverse the money and I told her what I just stated above and she asked if I would to cancel the policy I said yes please and she told me that my policy would be cancelled and I will receive a message but I never got the message and then yesterday R320 was debited from my account and I tried calling your offices but I was told that I should not hung up and wait for someone dealing with these kind of issues to assist me I waited more than four minutes but no response and my airtime was finished now I received a notification from the bank letting me know that another R320 was debited from my account that makes it R640 an still I fail to understand because my IFA policy was cancelled in July. I feel like I'm being ****** my money and no one is doing anything about it. Amazingly it only take you few seconds to authenticate our cards and debit our money but it takes you forever to cancel the policy. Please respond as soon as you see this message
