Dell Inspiron 1545 — UNRELIABLE to purchase from DELL

I placed the order with DELL on FEB 1 and Dell offered FREE NEXT DAY SHIPPING on the systems; 2 days later I got an email notifying the production delayed, then the next day they canceled my account with reason due to the shortage of the part and they were unable to fulfill their order; I was so mad because I bought this systems not only for me but for my other relatives; I called DELL customer service then they played the game transfering me around around until I completely lost my patient;
I don't know if this complaint cant be seen by DELL managers, but the way Dell does business or treats customers are unacceptable;
Dell should learn HP how to satisfy customers; I ordered HP laptop before and HP had the same problem; they sent me an email to notify the delay and for the compensation HP also offered $50 coupon for the next purchase; then 3 or 4 days later Hp shipped the system to me;
Here is the proof of DEll email:
