Who called from 20100020

Received text stating appointment confirmed with Egryn Ellis. No idea who or what this is. Message states to ring isign on 0845 1601680 if inconvenient.

I am fed up with these spam texts!

received text to make contact with somebody ive never heard of as she is trying hard to get hold of me

it was written  my child name and as he has to see a dantist and i have to call back to make an apointment

Also recieved a text from 20100020, 'Premex'.
Reminding me of an appointment. Dodgy because of weird number, I know nothing about this appointment.
They must be targeting me because I've had plenty if whiplash appointments recently.
