Yeah, bitcoin.com is a known scam site ran by known scammer Roger Ver. This is part of how he makes his money - tricking newbies like OP in to buying his trash altcoin while thinking they are actually purchasing bitcoin. It is highly deceptive and highly untrustworthy. OP isn't the first and won't be the last to fall victim to this scam, unfortunately.

To OP - is your wallet a multi-signature wallet, some other script, or just a standard "nested segwit" wallet? How did you create it? Depending on if it is or isn't a segwit address depends on how easy or not it will be to recover the coins.
