21 Unauthorised debit orders left with bank charge

On 27 November i realised that unauthorised debit orders went off my bank account all ranging from amounts between R1200 and R2500, after my bank account was emptied by the unauthorised debit orders i received a further 18 sms'es from absa requesting to deposit money into my account for these debit orders to go off leaving me with 21 Unauthorised debit orders that was loaded onto my account. I went to absa for 8 days in a row reversing the debit order only for the next 4 to go off as soon as the money was reversed, due to my account not having sufficient funds for all 21 debit orders to go off they bounced and i am left with bank charges amounting to approx R3500 the branch said they are unable to stop the debit orders and now say that i should request this charges from the company who debited my account but i feel this is ABSA's responsibility not mine why is unauthorised debit orders going off my account when my money is supposed to be secure.i am now left with charges i cannot afford to pay and a bad record for bounced debit orders. This is unacceptable and to make thing worse i gave birth on 11 November and had to take my newborn to the bank everyday with no luck! Not happy!
