American Express unacceptable customer service, nasty, unresponsive, more loyal to fraudulent company than to consumer Ripoff nationwide

I have been fighting with American Express to dispute the charge for a sofa I ordered back in December that I still have not received. I originally filed my complaint with them back on March 8th. They are inaccessible on the phone. They took days to call me back and then would not leave last names or extensions. They kept saying that there is nothing that they can do about my missing sofa because my contract says that shipping times may vary even though it has been over 5 months and the sofa company(Leatherland USA) is completely inaccessible to myself, the Better Business Bureau as well as the attorney General's office. The sofa company has already lied three times to American Express about shipping times but American Express believes them and still refuses to help. They can also be very nasty.
