You would probably be more likely to get a replacement card by stopping by your bank or calling them. Generally, they need to confirm who you (to avoid identity theft) before they will issue you a new card.
My Visa debit card has expired and I would like to write a request letter to the bank manager to issue a new one?
You can renew it without any problems. This is exactly what I did with my visa through the Russian American consulting travel agency. I needed a Russian visa NYC. That so easy.
