No. Most of it is just a bunch of bullshit.
is it really there will be no information available over 2000 blocks?
No. All the information will remain on the blockchain and on your fully synced node permanently.
private secret view keys are attached to address (mnemonic) right not the transaction?
"The private view key" is not limited to a single address or transaction but rather applies to all addresses within the wallet. Think of it as a private key for creating a watch-only wallet, it cannot be used to sign transactions, but it shouldn't be shared publicly to protect privacy. On the other hand, there is a "transaction key" that is unique to a single transaction and can be used to prove that you have initiated the transaction.
is monero wallet really loads 1 month mostly?
The reason your wallet is taking so long to sync could be due to a variety of factors. Are you using a normal or lightweight wallet? Are you running a full node or using a remote node? And how's the performance of your hard drive and internet connection? These things can all play a role.

As I mentioned earlier, it's a bunch of nonsense. If your wallet is synced and you can't see the transaction or if the sender can't show the TXID and transaction key, it's a clear indication that he's lying to you.
