I wouldn't use Bitcoin.com's wallet, or read any of their news at all. That's Roger Ver's propaganda website. Get Electrum for BTC (and Electroncash for BCH, I think).
Having said that, are you sure you bought BTC and not BCH? Thanks to the BCash idiots, a lot of noobs are sending BCH in BTC addresses, or BTC in BCH addresses, because the address format looks exactly the same.
You need to go to blockchain.info or any similar site and post your tx id to get further help.
