unauthorized debit order

i just noticed that the company with Ref Amani Life is trying to deduct the amounts of R400 ,R99 and R29 on my capitec account which i never authorised , it has been going on since Feb nobody ever called me to sell me anything from the company but they go and debit my account . To make things worse I changed banks last year June and moved all my debit orders so i don't have an agreement with those people since they started debiting the month of Feb even the debit date is the date i don't give to companies i have an agreement please help because this company is just helping themselves with peoples money. i am not their client and have no intentions of becoming one so please stop debiting my account .
