WORST BUS SERVICE AND CALL CENTRE

MY PARENTS WENT TO SHOPRITE TO BOOK TICKETS FOR 9/12 FROM HEIDELBERG TO MARGATE. THEY WHERE TOLD THE BUSES ARE FULL. WHEN I WENT ON INTERCITY WEBSITE I SAW THE BUSES WERE NOT FULL. I THEN CALLED THE CALL CENTER AND THEY CONF THAT THERE ARE MORE THAN ENOUGH SPACE, I THEN ASKED FOR THE TICKETS TO BE CHANGED WHERE THE ARROGANT CALL CENTER LADY TOLD ME I HAVE TO PAY 20%...I SAID NO BECAUSE ITS NOT OUR FAULT AND SHE SAID WELL ITS NOT THEIRS EITHER, AND SHE WILL NOT LOOSE HER JOB FOR ME. I ASKED FOR A SUPERVISOR SHE SAID THERE ARE NONE, I ASKED FOR THE OWNER OF THE COMPANY SHE SAID HE IS IN CHINA. SHE KEPT ON INTERRUPTING ME WHEN I SPOKE TO HER, WHERE I JUST DROPPED THE PHONE. LAST TIME EVER I WILL USE YOUR SERVICE!!!!!
