Child exposed to pornographic image/content on suggested audiobooks

[GT1001]

Has anyone else had their child exposed to pornographic image/content on suggested audiobooks when explicit content is turned off. I have been on the support chat and I am supposed to be getting an email through from the team it was elevated to. This was nearly two days ago. It had disappeared but it has come back again. This really is a serious safeguarding issue and I feel it needs to be dealt with faster - any ideas to get it removed quicker?
