Upgrade Process

I've been trying to upgrade on my current contract. On the 3rd Oct 2015 i walked into the Store to do an upgrade, just to be told the application will take 2day. Today i went back to the store as no one has come back to tell me if the application has been processed. Again i'm left disappointed as the application has not been done. Not even the store manager can tell me when this will be sorted out. On top of that they want me to call the regional manager. Poor service even worst telecommunications company. I will advise everyone not to take up any contract with this mobile service provider.
