Traveling Dartford to St Olaves

[angelface]

Anyone know of a coach service that takes from Dartford to St Olaves?

I know bus 477 goes to the Orpingtion town centre but during the school runs I'm imagining it would take about an hour to get there.

I've Googled a coach company that says they go to St Olaves but they never answer the phone!!!

Thanks in advance
