You seem to be leaving out braces on your if statements. It was really easy to find with the code auto-indented. Here's a code excerpt:

switch (pkgType)
    {
      case 'A':
        if (hours > ONE )
          cout << "Package A " << PRICEA << hours
            << cost << endl;
        cost = PRICEA + ((hours - ONE) * EXTRA1);  // this will always get run
        break; // this will always get run
        // everything below this is unreachable code
        else if (hours <= ONE)
        {
          cout << "Package A " << PRICEA << hours
            << cost << endl;
          cost = PRICEA;
        }
        break;

That happens in all the case statements. I think you want something like this:

switch (pkgType)
    {
      case 'A':
        if (hours > ONE )
        {
          cout << "Package A " << PRICEA << hours
            << cost << endl;
          cost = PRICEA + ((hours - ONE) * EXTRA1);
        }
        else if (hours <= ONE)
        {
          cout << "Package A " << PRICEA << hours
            << cost << endl;
          cost = PRICEA;
        }
        break;

which could be further reduced to this:

switch (pkgType)
    {
      case 'A':
        cout << "Package A " << PRICEA << hours
             << cost << endl; // this line was the same in both the if and else
        if (hours > ONE )
        {
          cost = PRICEA + ((hours - ONE) * EXTRA1);
        }
        else if (hours <= ONE)
        {
          cost = PRICEA;
        }
        break;

btw, for future posts, please put your code between [code] and [/code] tags to preserve formatting for the rest of us. Also, posting the error message is usually quite helpful ;)

Thank you so much i really appreciate your help and will try to do better on my future posts! :)
