Bank statement and change of address

I went to change my address on the 9th October 2010.The staff of LLOYDS Tsb in harrow station road said yes it has been change from the old one to the new one. Unfortunately, since I was waiting for my bank statement with the new address in Novemeber, I never got it. Went back to the lloyds bank again today which is 3rd Dec 2010, my address was left the same, and it has been changed just now, and because of their mistake, I have to wait for another week for my bank statement. I dont understand,if the staff dont their job, who is going to do it. I requested my bank statement, saying it is urgent, but no, nothing was taken into consideration. I have to go 4 times, on my day off, then today calling the complaints department, to sort out the staff mistake. It is a  waste of my time.
