Hassles when upgrading my contract

I went to the Vodashop on the Campus in Bryanston to upgrade my contract in the morning of Friday 11 March. I was told the Vodacom Finance has to approve the upgrade for some reason which could take up to 24 hours. I tried calling the shop multiple times with no answer after which I went to the shop which I am not complaining about because a walk does me good. I was told that the upgrade would not be done by the end of the day I accepted that the approval would be done on Monday. Monday Morning I walked into the shop and was told that the approval was not given yet but the manager of the shop has escalated the query. When I walked onto the shop on Monday afternoon I waited for close to an hour while the consultant waited for someone to answer the phone at the call centre and then that I must come back in an hour and everything will be sorted. When I went back an hour later I had to wait another 30 minutes for the call centre to answer the phone after which I was told I need to wait another 24 hours, when enquiring I found out that the request that was logged on Friday could not be tracked and a new requests had to be logged.
