Tech support scam number 1 805 334 5699

My mom was looking for tech support and found this number (above) and they scammed her out of almost $7000. It happened this past weekend and she has already taken steps try to fix this (gone to the police and contacted her bank). She informed me that the number is attempting to call her again, I advised her to not answer and to let the police know the scammer is trying to contact her. Please help.
