FNB, please get your story straight!

I ordered a laptop last week from the FNB device options list. It started with my application not being processed as it wasn't completed (yes I did save it to have a think if this is what I wanted) then I couldn't get back onto my saved application,only to be called and told that an application doesn't exist. Ok, abit frustrating but it got sorted.Then I was told that the courier company would contact me in advance to organize delivery (as I wasn't getting it delivered to my address) I then was reassured that I will be contacted the morning of delivery to set up a time, this didn't happen. What did happen was that the courier just arrived at my moms house this morning, with no notice, no phone call, and my mom wasn't home, they told the housekeeper that ONLY I CAN SIGN FOR THIS NO ONE ELSE. then why was I told that my mom needed a copy of my ID and hers for delivery to take place, why was I **** to that you would contact me to set a time for delivery. WHY HAVE I BOTHERED TRUSTING FNB??? I am sick to death of this lack of service, I have constant issues like this with FNB and Ive only been with you for a year! SORT THIS OUT TODAY!
