It might be that Swaprol migrated to BSC from Ethereum, or vice versa. It happens quite a lot lately so that could explain having tokens on two separate blockchains. Regarding the different token price, that might be due different exchanges where BNB and ETH versions of tokens are listed/ and that's another thing that is not uncommon.
If I am you, I would check their website whether team is real (revesre image search their team members) check the whitepaper etc. And try again asking the question about having two tokens of two different blockchains.
If they are deleting your texts from their telegram channel then something is wrong here. I will suggest you to research little more before making any investment or joining their tokensale. I will suggest you to add their official website and telegram link on your thread which will help thread visitors to take a faster visit on the website.
Deleting messages on Telegram doesn't have to mean that there is something wrong there, what is also important is the way to ask the question. If you just get into the group with scam accusations, chances are your messages are going to get deleted as admins are usually trigger happy there and don't have a patience to communicate properly.
