MWEB PATHETIC SERVICE

I AM TRYING TO GET HOLD OF MWEB TO CANCEL AN ORDER I HAVE PLACED . I WAS TRANSFERRED THROUGH TO SIX DIFFERENT AGENTS/DEPARTMENTS AND STILL NO SATISFICATION. ALL THAT I WANT TO DO IS CANCEL THE ORDER I PLACED WITH MWEB. I WOULD APPRECIATE IT IF THEY CAN CALL ME TO CANCEL THE ORDER
