Mistake in ordering Camera Add-On

Have just set up my MEII mount after storing it for 4+ years. That's another story ...

I had forgotten that TheSkyX when I ordered it came with T-Point and the Camera Add-On included.

I mistakenly thought I needed to order the Camera Add-On and so have paid $150.00 unnecessarily.

Grateful if my card could be recredited with the £150.00 as I already have a serial number for this and so do not need a second one!

Thanks in advance.
