Upgrade of Telkom Moblie COntract

I've being trying to upgrade my contract since 27th Feb 2022, the system requested credit vetting, but after 2 weeks no feedback received so I canceled the upgrade on 11 March 2022 . On 12 March 2023 I called Telkom directly to do the upgrade again, the same thing happened again, the system requested credit vetting and I waited a week resulting in ne cancellling the upgrade. I attempted again on 28th March 2022. the agent told me credit vetting takes 72 hours. I just called Telkom now and the upgrade is still pending outcome of credit vetting, the agent advised it takes up to 1 week. I am confused and frustrated, irrespective of the outcome I would appreciate feedback whether it is negative or positive. Also how can the agents advise me differently..one says 72hours the next one says one week. I really need feedback as to what the actual problem or delay is.
