Nah... no use. The fact is, the mall rented out the space to the advertising/media company. The mall will have limited say over it... and furthermore don't expect customer service to offer much enthusiam... this is beyond their scope of work.
I remember about 5 years ago... I saw a dying Black-tip Shark at Wisma Atria, I was so concerned, I went to the Customer Service and reported to them... and I get that "that's none of our business" response from them
