overdraft decllined yet again

i have been trying to get an increase in my overdraft for the amount of 1000r i earn before deductions with my new increase 43 858.00 each time i phone in too apply they my expenses are too high well is this not the reason an over draft is in place and considering i have been a client for many years i find this most unfair.<br> i went to FNB who looked at my expenses and said they could give me an overdraft for 15 000 where ABSA can only give me R7373.00 makes no sense to me .... the money is getting payed back why offer such a service to be declined by it each time i apply .... grossly unfair
