Havent received Avax sent from C chain Avax wallet to my Metamask?

Hey guys i followed a video of a guy which he directly sent his avax through his Avax wallet via the C chain network to meta mask directly to his meta mask wallet. This was without making metamask compatible for Avax prior to sending it. I will list link to video below:

I did exactly the same but havent received my avax in my meta mask wallet. Is there any way i can retrieve my avax back?
Many thanks,
