Unbelievably Bad Service

I ordered a laptop through FNB. I received an sms from Digital Planet informing me that my device will be delivered on the 1st of October and that I should log in and confirm my address. So I did. As I work from home, I gave FNB my home address. When I logged in I could change the address, so I did, to my office address as I have meetings on the 1st of October and will be at work. Monday morning, 28th of September, I receive an sms telling me that my device will be delivered that same day between 9 and 3. No one pitched up at work or at my house. I called just before 3h to hear what was going on, they told me it will take an extra day because I changed the address. Fine. Woke up this morning with an sms telling me that I should call the call centre, because I was unavailable for delivery my order could be cancelled. WHAT? They did not deliver at either of the addresses that they've got. Now I call in and they cannot find me on the system and says I should phone FNB. Not a happy customer! My ref number for my call was fnb211752.
