FALSE ADVERTISING

I AM TOTALLY DISGUSTED BY TAKEALOT.COM'S SERVICE. I PLACED AN ORDER ON THE 9TH OF FEBRUARY AND PAID IT ON THE 10TH TO DATE I STILL HAVEN'T RECEIVED MY ORDER.THE ORDER HAS BEEN DELAYED MORE THAN ONCE.THIS MORNING I GET AN E-MAIL TELLING ME THAT ONE ITEM ON MY ORDER HAS BEEN CANCELLED - THIS IS NOW THE WATER PRESSURE PUMP I SO DESPERATELY NEED - THEY ONLY WANT TO SEND ME THE PRESSURE CONTROL PUMP WHICH I CANNOT USE WITHOUT THE PUMP ITSELF.WHY DOES TEAKEALOT ADVERTISE THE ITEMS IT CANNOT SUPPLY???
