Caller: Unknown number

These random numbers call mainly in the afternoons. No message left. Don’t know who it’s from and given that over the last few weeks more of the same. Some perporting to be from Ampliphon that bunch doing the advertising for their new super hearing aid. Now one of their bunch is doing the wrong thing. Hang up or don’t answer but do check with here. They think they are being sneaky but given that they are using a number generator for a particular state or city and leave no message, they are by their actions leaving a very clear footprint by which we can to a high degree of accuracy identify themselves.
