first of all i wouldn't panic too much. As someone already posted it seems like that there are some problems on ledgers side regarding Bitcoin Cash. You should get in touch with vender you bought the ledger from.
As far as i know, ledger as a company has 0 access to your personall addresses/wallets as soon as they are packed.
Are you 100% sure that you have sent the BCH (Bitcoin Cash) to a Bitcoin Cash address and not to a BTC (Bitcoin) address?
*edit*
Ok seems like you already figured out what was wrong:
Good to know your funds are OK.
But I must say I'm flabbergasted Ledger would do something like that without real time updates plastered over every possible outlet informing everyone what's going on. There could've been millions of dollars' worth gone missing in certain cases and people wouldn't have known what the hell was happening.
