Unauthorised debit orders on my Savings account

I have a savings account with Capitec Bank. Lately, there have been many unauthorised debit orders on the account. The ********** are very smart because they know that the debit ord ers are less than R100 do not send any notification/sms on your mobile device. There's Lovingthyyourhelp which has been taking R50 from my acccountevery month, Iga Investiga which changes references every month when taking my money(R99.00 and R98.00), Khukule(R89.99) and Stero Kukul(R99.00). I do not have knowledge of who this people are and it seems like they have been taking money on the accounts of capitec clients. I need Capitec to investigate this people and recover all the money that has been ****** from me.I believe the bank is the safest place where our monies are protected. I want Capitec to recover all my money because it looks like its an inside job. I am prepared to take the matter to the releant ombudsman if Capitec does'nt stop this ****** and reimburse me the money due to me.
