Manta transaction didn’t work?! Please help.

Hi. I swapped some bitcoin for manta on changenow and I used my manta wallet to send the manta to from the swap. I copied/pasted the wallet address from my manta wallet into change now, the block explorer says it worked, but the coins never showed up. The wallet address used was definitely the wallet address from my Manta wallet because I just copied and pasted it. Any here who can help me figure out what happened here? Thanks

Also, if anyone knows of an exchange you can use from the USA or a swapping service you can use from the USA where you can buy or swap for manta Atlantic (not pacific) coin I’d really appreciate it if you could let me know the name/url (or any other way to get Manta Atlantic coins). Also, a better wallet for Manta Atlantic. Thanks again.
