Manager with unhelpful attitude

On Monday 23 April I visited Woolworths in Westville Mall. I asked the manager on duty to assist me with a gift card that wasn't working.

She didn't get off her chair to assist me, and she didn't read through the despatch note which I brought along (which contained the information about the gift card). Instead she insisted that she wasn't able to help me if the gift card wasn't bought at the Westville Mall store. She said that I would have to go back to the physical store at which it was purchased. If she had read through the despatch note, she would atleast have seen that it was bought online. She didn't apologize for any inconvenience, or seemed enthusiastic to try and solve the problem.

I shop at Woolworths on a regular basis and I am really disappointed that a manager should have such an unhelpful attitude towards a customer.
