Tracking is a waste of time and I wasted my money

I am excruciatingly angry!! SA Post Office have typical SA service!! I used the overnight Speed Couriers option and sent my package early monday morning +-9:30am and the lady said it will be there latest Wednesday. I have been tracking the package every 30min the whole day and now I see 17:44 when I track it that it magically has been at the post office since 14:20!!! Why the hell did they not notify the receiver and why the hell is it showing me now when I track at 17:44 and have been tracking the whole damn day that the package has been at the stupid post office since 14:20?? I have been tracking my package every 30 min the whole damn day and only now when they are closed does it show that the package has been there since 14: 20???!!!!!! I want my money bac****! There is no excuse. Now the package is going to be received 3 god damn days later!!!! I WANT MY MONEY BAC****!!
