Absa Vehicle Finance - Reposssesion of Vehicle

i had purchased a new vehicle recently with Absa Vehicle Finance, and due to my financial contraints I am behind on 2 months, I contacted Absa, but the unfriendly consultant, who refused to assist, told me my vehicle has been handed over and now wants to be repossessed. I contacted the person in charge and told him that I would be able to make the payment in the next week and the account will be up to date, but they have refused to assist me, and want to repossess my car, he has also mentioned on email that the bank wants to end the contract rather than proceed further, This is so unfair, how do you just end someone's contract based on 2 months, and if a person refuses to pay, I understand, but I acknowledged the debt and mentioned that it would be paid, all i wanted was a grace period and if by all means it isnt paid, please then do the necessary, but when a person is telling you that they will pay. I even asked for a debit order to be loaded onto my account for the outstanding payment and was refused. Now I am told that my car will be taken away and I will be liable for costs if I need it back. Its a longer process to get it back. Please can someone advise how is this legal? Where does it state in the contract that after 2 months, a vehicle will be taken away and sold.
