Sounds like your problem is with Bitcoin, not any single site.
"invalid" is what the blockchain explorer displays, so you should take your issue up with them.

Looks to me like you double-spent the funds (might have been a RBF given the confirmed transactions were broadcasted later and has higher fees).
Anyway, the transaction is unconfirmed and never arrived because you used the same inputs in a confirmed transaction that has been credited to your account.

Here's the two transactions:

Both those double-spending transactions that confirmed show up in your deposit history, they use the same inputs you used before in the unconfirmed transactions, which is why the earlier ones will never confirm and can be safely discarded.
No money was taken from you, all confirmed deposits were credited.
