Adding multiple class locations in Acuity

I have tried to contact support a number of times to be able to add multiple class locations into my Acuity settings with no reply.

In the support area it says:

To set locations by appointment type:

• Contact Customer Support and ask us to enable this feature.
• In Acuity, click Appointment types.
• Click an appointment type.
• Click Add a new location.
• Enter your location, then click Save location, then Update appointment type. 

But without Customer Support enabling this feature I'm stuck.  Can anyone advise me how I could do this myself?  I have new classes starting soon but with no functionality to vary class locations I can't take any bookings.

Thanks in advance.
