Disconnected account

I paid my account on the 26th instead of the 25th, I acknowledged that I was late I paid the reconnection fee. They disconnected my account on the 27th I contacted them they then reconnected. Now today it's disconnected again now I'm told that I should wait 48 hours. My question is why was the money not allocated when I spoke to them on the 27th when the account was first disconnected?
