Console.Read only reads a single character. You need to use Console.ReadLine.

Console.Write("Enter the integer the account number");
accountnumber = int.Parse(Console.ReadLine());
Console.Write("Enter the integer the account balance");
bal = int.Parse(Console.ReadLine());
Console.Write("Enter the account holder lastname");
name = Console.ReadLine();

You might also want to consider using int.TryParse instead of int.Parse so that you can better handle invalid input.
