SAU Double Debit

I had an insurance with SAU policy SAU ********** , on the 26th April 2018, i tried to cancel my policy with them as their access to fix my car from a minor accident was ridiculous, their assessor company (Professional Claim Service Solutions) came to assess the car after minor accident and their quotation was R28 528.10 and i was asked to fork out R19 000 for Access while the car was in good drive-able condition. I decided myself to fix my car personally and it has cost me under R6 000 to fix my car. To cut the story short i called SAU on the 26th April to cancel the insurance as my access my too high, i was given an option of paying R896.64 and voluntary access will be R5000. on the 27th April they deducted monthly premium with no problem. 30th April i took an insurance with MiWay Policy number ********** 2 as their cover was better than SAU and voluntary access was cheaper than them. To my suprise today the 4th SAU tried to claim R896.64 and R151 (SAUAPR2018) while April money was taken on the 25th April 2018. Guys can you please stop deducting from my account as i don't want anything to do with your service as it was horrible!! Please cancel my policy SAU ********** as i have MiWay insurance now Policy number ********** 2
