bitcoin.com has been scamming people for a couple of years now, they advertise that they are selling "bitcoin" but when beginners like you that aren't familiar with certain details go there and buy "bitcoin" they end up with an altcoin that this site has created and owns called "bitcoin-cash" and is trying to sell in the name of bitcoin because they have no other way of getting people to buy their shitcoin.
sorry to say that you were ripped off.
This is really sad another newbie a victim of their scams, @omess you should also consider taking legal actions against them for misleading you into buying BCH instead of BTC.
Sell your BCH and don't repeat your mistake.
how do I sell it ?
If you want you can open a thread out here in the currency exchange section and sell your coins here, also make sure the buyer is a reputed buyer or if he isn’t reputed then insist on using an escrow for this deal.
