Should/ can I change agency?

You should add "on the condition the CV is sent to the client within the next 48 hours"

But how do you know, 48 hours later whether it has or not? He's spinning me a line anyway, so he's going to tell me that it has been.

He's explaining the delay as client - agency - third party - agency - me.

Wow, what a chain.

When I have experienced just two tiers of agents it didn't work out well.
They tried to change the agreed rate, so in the end I had to tell them to go and multiply.

I would be tempted to swerve this one if I was you.
With that many agencies involved its likely your CV went nowhere as those agencies will have their own candidates too.

It allows you after that 48 hours to go with other agents. Ask the agent if you've been submitted, if not then go with them and let them put you forward.
