No feedback after being promised twice

On the 12-02-15 i called Absa call center requesting some document after being transferred from one department to another i finally got through a guy by the name of Lebo Ramorasi. While explaining to Lebo what my needs were he started to cut me off and did not give me a chance to explain what i required or even to check up my reference number, so i request his details and also his superiors details all of a sudden he became very helpful stating he will look into my query. He then put me on hold for over 20 minutes by this time i have been over 40 minutes on the line. i then call back speak to a Mcdonald Pietse who now refuses to transfer my call to the correct department as per Mcdonald his not allowed to transfer calls which i could understand why not. I then request to speak to Kim Delta (Team leader) could not get ahold of her, then i requested to speak to her supervisor who said the complaint will be attended to and i will have feedback by close on business to my surprise no one contacted me- so i called on the 16-02-15 was promised that i will received feedback by COB still no feedback called back @ 3:45 the same day and was promised i will receive a call but still no call.
