Since you've tried different solutions to no avail, it may be time to bring in a power washer. It should "blast" the mold away. You can probably rent one for a few hours and get the job done once and for all. Then treat the wall with mix of bleach/water to help it from coming back right away. -

You may not be allowing the formula enough time to remove the moss, and this is moss not mold.http://homeguides.sfgate.com/kill-moss-landscaping-walls-28693.html -
