Double debit from capitec funeral cover

Capitec bank debited my funeral cover with no luck of funds ,on notice I paid my funeral policy directly after a day or 2 of that they then debited the same amount that I paid.i then went to a branch in Boksburgto do a reversal cz I needed that Money for my car insurance urgently .you can't reverse ur money on your mobile app nor in the branch so I was finally promised that my money will be in my account max days 7 but till the following month today they again debited without even a reversal of the last month surplus. My question if you can't reverse money on your mobile app,and in the branch and head office who then needs to do it I need the money that was debited reversed today cz am already on a surplus and again it's my car insurance money . Capitec can't take care of their client*****R SERVICE ..... When u get cut off by airtime the consultant can't even call you back .
