Cellphone Contract Approval

I enquired about a cellphone contract online. I then went on to receive a phone call from one the vodacom agents instructing me to send my documentation to an email in order for them to check my affordability. Needless to say it's a month and a couple of weeks since I've sent the email and I am receiving a response telling me that my application has been approved. I am no longer interested in their service as I have made other arrangements. I'm very disappointed with their service.
