Matter not taken serious

Took my car in for service in April at Hyundai the glen, when I collected my car I just took it without noticing my key remote got damaged. I noticed when I went out of the car and wanting to lock that it's broken. I notified the lady that was handling my service and sent a pic on the WhatsApp. She said she'll speak to her manager and I never got feedback. I've been calling since and everytime she says she spoke to the manager they will get back to me, the manager has never gotten back to me. I feel they are taking advantage and not taking this serious. This week I called again and she says she spoke to the manager they will get back to me as usual and I still never got a call from them. So I don't know who is the fool now here.
