Bad service from BT NGEBS

THE MOST PATHETIC SERVICE BY FAR Truworths BT NGEBS. I VISITED A STORE TO PAY AND THIS NICE SHORT LADY ASSISTED ME. I ADVISE HER THAT I WANT TO TAKE FEW ITEMS AMF SHE ASK IF I HAVE MY ID MEANWHILE I DIDNT NEED MY ID WHEN I WAS PAYING THEY JUST ASKED FOR MY ID NO. I TELL HER YEAH IVE GOT FINE I GO TAKE THE THINGS MY BROTHERS NEEDED. MIND YOU I'M ON CRUSHES, HAVE A BROKEN LEG YET NOBODY CARES TO BRING ME A CHAIR OR ASSIST ME, THEY MAKE ME STAND ON QUEUE. THIS LADY OTHER CASHIER NOW TELLS ME MY ID IS TOO OLD AND SHE CANT ASSIST AND IF SHE WERE TO ASSIST WITH MY ID NUMBER "NDINGABE NDIYAKU GEZISA" THE LEVEL OF DISRESPECT AND I DON'T THINK THATS A BUSINESS LANGUAGE. TODAY I GO THERE WITH A TEMPORARY ID AND SHE SEES ME THEN SHE GOES AND WHISPER TO THIS OTHER LADY THEN WE ENDED UP BEING SENT AWAY. I'M SO SO NOT HAPPY WITH THE SERVICE WE RECEIVED. IF THEY CANT TAKE TEMPORARY ID'S THEN WHAT IS THE POINT AND IF THERE IS XDS WHY CANT THEY ASK SECURITY QUESTIONS BASED ON IT?
