Unauthorised Debit Order

Hello Peter<br> <br> I received an unauthorised debit order from Sabiflash for R99.99<br> I do not know what this company is about but I wonder how they are able to debit our accounts without authorisation. Surely that is ******* and **********. What can I do to ensure that it does not happen again?<br> <br> I lodged a complaint with my bank and requested the contact details of this company, *** / ***. I plan to give them a call today to give them a piece of my mind!
