They can't check if they have the item I want

I went to greenstone this morning to get the clothing for interview tomorrow, little did I know of the horror service I was going to get, when I get to the store I got the items I wanted shirt and pants, the problem began when I wanted shoes that was on the display, the lady by the name of Felicia who was helping me went check she came back and said she can't see it, the was another guy by the name of Enoc I gave him another to search for while Felicia was searching the both come back and said they can't see it, now they both went to system the lady said the computer doesn't have a keyboard and it won't switch on, Enoc gave it to someone on the counter to look but they couldn't, I asked Felicia to call sandton branch to check if they have, that too never happened, I was getting frustrated and I was like let me go pay what I have, when I get to the counter I get another horror, the lady who was helping me she told me to confirm all my details, I told her I am not going to do that I've done it in my last shopping, she said her system can't let her do my transition without confirming all my details, I told her that's how complicated to buy at truworths I won't buy,manager never helped
