Your song is important to us...
politically incorrect, check out an Aussie, Kevin Bloody Wilson (not for the faint hearted here and lots of swearing) his song Dicktaphone circa 1987 which is the ultimate of songs re customer service on the Telephone! I warn you again, language is not as the Queen speaks it.
But to your lyric, the chorus is actually what everybody 'already knows' and for mine is not the best vehicle to take this song forward.
I think this will work better if the Chorus was as simple as something like (this without changing anything else)i.e.
Customer Service
(Verse 1)
On hold for an hour
Patience wearin' thin
Then a voice from out of nowhere
Said his name was Jin
But, it was hard to understand
What it was Jin said
And he put me back on hold
When the line went dead
(Chorus)
Murders back in me head when they said
can I help you, hold the line please
waiting, greensleeves, waiting
frustrating, waiting
your calls important to us
waiting, waiting waiting
(Verse 2)
The second phone attempt
Left me in a daze
Got bounced around from here to there
Spinnin' in a maze
When I finally got someone
I was told to go
Online to find the answer
No one seemed to know
(Chorus)
Murders back in me head when they said
can I help you, hold the line please
waiting, greensleeves, waiting
frustrating, waiting
your calls important to us
waiting, waiting waiting
(Bridge)
To speak to a 'live' person
Might leave ya' cursin'
Thousands of miles away
In Manilla or Bombay
(Chorus)
Murders back in me head when they said
can I help you, hold the line please
waiting, greensleeves, waiting
frustrating, waiting
your calls important to us
waiting, waiting waiting
GOODBYE - FOREVER
Yours as always to do with as you like
Arty
