Promised Higher Pay But Nothing Yet

i don’t want to give out too many details but i onboarded less than a month ago or so and before starting i was promised by the DM would be getting **/hr but instead i’m making 3 dollars less than the initial price. what do i do beside go to manager seeing this is the second to third time im asking? it’s not looking like i’m going to get this resolved anytime soon unless you guys know of a quick fix i can use
