Vodacom contract declined

Hi. I app**** for a new contact yesterday via facebook online application, you guys emailed saying that yourl going to do a credit check and get back to me which didnt happen I called the call centre today they said it was declined due to my credit rating.....I checked my credit rating on clear score which was 572.....just above average in my area , but the reason for my rating is that I took out a contract around 5 months back with vodacom which was around R175 pm and it does not reflect on my credit profile that I have a contract and being paying well , and also I added alot of extras from vodacom such as voice bundles and cell phone insurance etc now my bill is around R505 per month which is being paid for and never missed a payment..... I guess the payment history with the company counts for nothing as I'm still declined for a new contract so i decided to cancel all my extras and just pay me R175 pm or maybe even cancel the contact itself also n pay of the device thanks
