Bad Servise

Went to Key West branch last of last week to apply for a contract tablet. Was told that my documents still need to go to ***** department for investigation before approval and I was told that the process take only one day. Guess what till today still waiting for that one day to pass. This is totally unfair. Called head office and was told to go back to the same branch to ask why is it taking too long and went back using my petrol, my time and they promised to call me on Monday. I'm still waiting for that call till to date. Poor service I received I could say. Why can't they tell me that they are unable to help me and stop wasting my time? Please can someone do something about this?.
