Unauthorised Debit orders

I am so sick and tired to be a victim of debit order *****s. This has been going on for the past 2 years. Every time i stop and reverse it at the bank but they keep coming back. no one in the call centre can give me clear answers how this can be stopped. All they suggest is to keep a clear eye on my statements, Seriously!!! I sometimes miss it, than the long request form is required to be filled in to have it reversed. Different References are used as MARKAZI 1CH0C, DIGICASH140915, SMARTCARE, SAS***, KIANGA3 _***, The latest transaction was on 30 November 2015 with reference AQUARIUMIV9241AQUARI52 151130. I'm based in cape town, but these references keep tracing back to Durban with contact numbers that doesnt exist. Amounts all below R100 and no sms notifications when these transactions are done. I feel helpless and frustrated. please assist in this matter urgently.
