Got a home phone (landline), it never gets plugged in, because anyone who matters has my mobile, and secondly, it's all nuisance calls - and from the beginning calls from debt companies chasing some woman. There's calls for her many times a week - nearly 5 years after taking over the number.
Only ever get one company pretending to be a claims for accidents service on the mobile, and that is easily blocked, plus I'd demand the mobile company change the number if it ever got worse.
They can all sod off
