Please, help to solve the issue:..

I created seven Segwit addresses (in June 2021, apparently, they were changing from Legacy to Segwit at that time) in the Blockchain.com Wallet, sent them to the Sender, transactions were made (they have status "Confirmed"), however, there is no balance in the Blockchain.com Wallet along with no evidence of Used and Unused Addresses.

Please, advise the way to recover funds and shift them from Blockchain.com Wallet to Electrum or elsewhere..

Thank You.
