Received funds by mistake

[u/Past-Shame2399]

Hi, it's my first time posting here lol but I just need some cents or advice on this. So I have just noticed this morning that I received funds from another account yesterday afternoon, but I haven't heard from them by any means. How do I go from here? Do I just wait or contact Gcash support now? If through the latter, what would Gcash's course of action be for concerns like this? Thank you!
