***********, unhelpful staff and Bad attitude

Went to the store on Sun 05.04.2015 to enquire/exchange an undergarment (underwired Bra) whereby the wire had broken in half and could be due to factory fault. Item purchased on my account end Dec 2014, did not keep the receipt. Spoken firstly to the attendant in the Lingerie department who advised that I should take a new item and take it to exchanges. The teller at exchanges firstly had to try to find the trans on system, she kept bringing me printouts of purchases made which none reflected the purchase. at one stage I was brought printouts of someone else's account and had to scan thru this myself, the teller was extremely unhelpful and clearly just wanted to get rid of me, she then called Simon, a supposed store manager who was even worse, at some point he ignored me. It took about an hr and a half to find the trans, which I helped find looking at the accounts screen, this could have taken 10min if they valued their job and had knowledge on Customer service, the attitude was appalling and at some point rolled their eyes at me. I lodged a complaint with Mr SC Pursell who seemed shock at the time I stood there, I would like feedback before I approach the Consumer Protection forum
