Hi there,
Please ensure that you set up a Bitcoin Cash sub-wallet within your Bitcoin.com wallet if you have not done so already; there is a video tutorial below for your convenience on youtube, after the adress: watch?v=MyQwUJjTcNY
You will then be able to retrieve the BCC sent to your Bitcoin.com BTC wallet using the following tool (note that you must enter your Bitcoin.com BTC wallet 12 word recovery phrase into this tool): https://blog.bitpay.com/bitcoin-cash-recovery/
Please note that you will need to translate your receiving Bitcoin Cash address (from your Bitcoin.com BCC wallet) to an address beginning with the letter 'C' using the following tool: https://jdonadio.github.io/address-translator/
In the second tool above, paste your Bitcoin Cash receiving address from your BCC wallet and copy the new address beginning with 'C'. Return to the first tool, and enter the new address beginning with 'C' as your receiving address. Once you complete the transfer your BCC will appear in your Bitcoin.com BCC wallet.
Regards,
ENjoyyyyy
