********** double deductions

I recently took out a funeral and life cover with Absa Life in March 2019 the start date of these is 01 April 2019. March the 23rd 2019 R213.05 was deducted off my account as they say that the policy must be paid in advance. My mother passed away on the 29th of March 2019 and my policy reduced to 174.02 meaning that (I paid a premium for my mom even though she was dead) end of April I added all my family members on the funeral policy and my premium increased from R174.02 to R387.04 the April debit order did not go through so in May they deducted R174.02 + R387.04 = R561.09 that was fine, on the 21st of June I received and sms stating "YOUR POLICY COMMENCED ON 01/04/2019 AND THE NEXT DEBIT DUE ON 23/06/2019 WILL INCLUDE PREMIUMS FOR 06/2019 AND 07/2019 FOR ANY QUERIES, CALL ***. FSP36116".

I did not understand the sms so I called the number, the lady that assisted me confirmed that my policies were up to date and the sms must've been a mistake, Sunday 23/062019 a double deduction went off my account and amount of R774.14 and another one for R294.90, I just spoke to Brendon the manager and Benny the agent (ref: ***) and they say that when I added my family members have been added fro 01 April 2019 hence they have double debited my account. how hell would this be I mean they have no right to double debit my account without a detailed explanation, I called for an explaination immediately when I received the sms and they confirmed that it was a mistake, I did not budget for a double deduction and I feel it is very unfair that absa decided to recover funds that were supposed to go off in April only now in June without even telling me, because the sms sent stated that its for June and July premiums and now they are saying the premium is for April, I want Absa to refund me because their information is misleading and they did not follow the right ways to inform me abou what is happening to my policies, I need a refund on both the Life cover and the funeral policy because they double deducted on both.
