****** phone on flight during cleaning

I recently travelled in a flight from PE to Jhb on 5 May 2024. However, unfortunately so, one of the children I was travelling with forgot their mobile phone on seat 4F in the pouch at the back of the seat. We realised this within an hour (en-route to another destination) and contacted Airlink. We were informed that they await the cleaning service to return all lost items. I contacted Airlink daily, only to be told nothing was received. I received a call from one lady asking if the phone was a Samsung, I informed her it is a navy Vivo. Just for understanding - the phone is for a minor and is installed using Google Family Link, so no unauthorised activities can happen on the phone (tough luck for the *****). When we checked the phone within the hour it was on, then switched off at 76% within the 2nd hour. It requires a code in order to open anything on it, so the ***** cannot use it. Airlink says, blah blah, they cannot find it and no appetite to action or hold the cleaning service to task. As an Emerald member of their airline, I am really appalled that they condone acts of theft.
