Credit Vetting Issue

On the 28th of August I decided to get a new cell phone contract with Telkom. After applying the first time and not hearing any feedback, I decided to go in-store to reapply again, which than after, the application was forwarded for credit vetting, which would take 3 days. I have a great credit record, all my payments are paid on time and even extra. So I don't get why it would take a week. To mention that I have three Telkom lines that I use is simply disappointing with the service that they are giving me. I need this issue resolved as this is very disappointing. They are many networks willing to provide better services.
