Unprofessional

They are calling under false names to get your contact details, is this even legal? Changed my number because I got harrased daily with phone calls. I got a call on my husbands phone for a delivery, demandrd my own number and address. A day later HP attorneys starts calling my new number that no one has, not even my family. So this tells me that they are phoning and pretending to be a courier company to get your details.
