Help with getting matic mainnet

Hi, Im in a muddle and spend many hours trying to sort this out.
I wanted to move smartchain to matic mainnet. Did the transaction but did not go through as did not have any Matic mainnet to cover the transaction so its just sat somewhere waiting im guessing.
Ive spent a long time trying to get matic mainnet to cover it so the transaction can then continue but always hitting a dead end.
I have Matic in my eth mainnet and thought i would move that to cover it but again hitting dead ends and nothing seems to go through.
I really dont know what to do know and hope someone could help.
All i need is to get matic mainnet so the transaction can go through.
Any help would be very much appreciated.
