Pat has been dealing with someone targeting her with phone calls. Leo says it's not likely a stalker, but there's a scam called 'call spoofing' that uses robo dialers to try and get you to answer. But she says that they can break into an existing call. Leo says that's likely call waiting. There's not much to be done about these calls. Pat can try and block the call on her cell phone. She can also try and change her phone number, but that likely won't help either. Pat should contact her cellphone provider and see what solutions they can offer.
