It was a NPC hiding in a building. Asking for a goldduck for lickatung. How can I re - get TM rock smash. I need it to move rocks :(

I'm having a big bug/glitch on my account. I went to get TM rocksmash, I traded the NPC to get it and it didn't go in my bag. Another one is I traded goldduck for lickatung and didnt receive it. I lost my goldduck.
