1st installment deducted 1 day after registratio

How on earth is it possible. Our bond is registered on 29 February 2016. On 3 March 2016 our first bond payment went off. We moved into our property before the house was registered inour name which means that we have to pay occupational rent which is the same amount as our bond installment. There is no way that we can afford occupational rent and an installment in the same month. Really????!!!!! This is absolutely rediculous. Is it the procedure to deduct the 1st installment 3 days after registration or is it only Nedbank....??
