Woolworths quality control non-existent

I returned the dress today to the Garden Route Mall, I was very disappointed, the one sleeve was shorter than the other. My question is, who’s doing your QUALITY CONTROL?? A lady named Natasha Malherbe went out of her way to find me another dress. She really spent more than half an hour on the phone to Langeberg Mall and Mosselbay Mall. A person at Langeberg Mall got our hopes up and said they have 5 dresses (size medium) but they can’t keep one out for me because it went on SALE… I was going to drive there to buy one….hoping by the time I get there that it will still be available. Just before I left the Garden Route Malls Woolworths, someone from Langeberg Mall phoned Nastasha to say that she made a mistake and they don’t have this dress. I’m from Sedgefield, and already drove to George. My question now is, WILL YOU BE ABLE TO FIND ME THIS DRESS IN A SIZE MEDIUM without any quality problem?
