My account being debited twice

I was called by the clientele agent in April 2013 for a funeral cover and we agreed that i pay R129 for my Fiance our two kids and myself ,the debit day came and i was being debited twice meaning that i was being debited 129+129 this happend for a couple of months until i called them and complained i then recieved a letter directed to my fiance saying that she was covered by clientele and her premium was R129 and the banking details on paper was mine,i do not understand how Clientele was debiting a person that i had covered a seperate amount and that was going off my account.my fiances details as well as my kids were misspelled,i kept on emailing them and asking questions that i was never given a straight answer,i do have the letter sent to my fiance by Clientele and she has never taken out a policy with them i did.so my question why was someone that i had coverd being debited a separate subscription?2ndly why was two debits going off my account instead of one?that sure constitutes as *****,i want all my money that clientele has been *******ly debiting from me paid back in the same account it was taken from
