Locked in a fitting room

After work I decided to go to Woolworths Randridge Mall, got something to try on and went to the fitting room, the lady sat and saw me go in, not even 5minutes later I come out to a locked gate. My boyfriend luckily returned and rung the bell, unfortunately the key was not with her, and she had no idea where the key was. Finally after waiting 10minutes, I called the manager from my phone to sort this out. Came down all apologetically and they went to fetch the spare key, alas no spare key but a a hammer and a ***** driver. I got the apology from the workers there but that does not give back the time and inconvenience! Also are your staff not meant to check the fitting rooms before locking it? I understand people are tired and they want to go home but there was still an hour before locking up. This is not customer service.I have never been so angry and close to tears and humiliated because of this!!!! I will not be returning to this store again!
