Rejected application for overdraft

We are an Accounting and Tax services company. We currently hold national contracts with two of the big four banks in SA, to supply them with Tax services. We are currently growing at a rapid rate. For one of the banks, we now supply services for all over South Africa, when, at beginning of this year, we only started with one branch in SA. For the current financial year, we are already in excess of a turnover of +R1.1 million. For the month of November, we achieved our highest month turnover to date. We are estimating a turnover of +- R1.5m for the 2015 year. To service these expanding national service delivery contracts, we are in need of an overdraft facility of +- R150000. This is due to make sure that there are no cash flow issues from beginning of next year. We purchased a software program to manage all files, and new staff are also joining the company from next year. We also joined associated bodies, applicable to our services, to enhance our services to the banks. Our bank account is one year old now. We are also willing to provide cession on life policy as security, if needed. The feedback today was just, NO, declined due to ''high risk''.no other reason given
