Caller: no call, number given in email

I keep receiving emails from Local Solar Deals. Today I thought I'd ring the number provided in the email. Had it been legitimate I was going to tell them to stop sending and unsubscribe me immediately. However, when I dialled the number copied exactly from the email there is a message saying I "can't be connected to the number as dialled".
Email is in my junk folder and will be deleted - so be wary of any calls from this number, or emails from Local Solar Deals <offers @ localsolardeals.com.au> Most likely these are scamming scumbags.
