unauthorised debit orders under R100

I have in the past year been getting random debit orders on my bank account under R100. when I go through my bank statement there will be some company I do not recognise debiting my account for amounts lower than R100, recent one is R99.99, I would then call the number on the transaction details and they will then refer me to another company, this time I was referred to J&A Solution tel: ***, ***, who said that they are running debits on behalf of telemarketing companies (I never buy from telemarketers) they would then promise to return my debits, lady Janet at J&A promised this.<br> <br> My problem is, why is FNB letting unauthorised debits through? this is now the 5th time and I'm rather tired of this. <br>
