Where collection points are close together, you need to zoom in on the map to see individual collection points. Tap / click repeatedly on the plus sign on the map to enlarge it, or pinch your fingers on the screen and then open them to zoom in on a touch screen.  Move the map by holding down your finger / the left mouse button and re-centring it to your location. Click / tap on the blue map pin closest to you to see the address and contact details for the collection point.
