BRICKS 4 ALL - VERY BAD SERVICE

I ORDERED PAVING BRICKS AT BRICK 4 ALL ON THE 15TH OF JANUARY 2016. I HAD TO IMMEDIATELY PAY THE FULL AMOUNT OTHERWISE THE ORDER COULD OT BE DONE. UP TO TODAY, THE 2ND OF FEBRUARY 2016 THEY HAVE NOT DELIVERED THE BRICKS. ACCORDING TO THEM THE BRICKS WOULD HAVE BEEN DELIVERED ON THE 21ST JANUARY 2016. WHEN I CALL THEM THEY DON'T ANSWER MY CALLS. WHEN I CALL FROM 'N UN-NONE NUMBER THEY ANSWER AND AS SOON AS THEY HEAR ITS ME, THEY PRETEND THAT THE TELEPHONE SIGNAL IS BAD. DUE TO THEIR BAD SERVICE THE BUILDING PROJECT IS STANDING FOR MORE THAN 2 WEEK AND I AM FACING BAD PENALTIES WITH THE PAVING COMPANY.
