I'm sorry, but no. Calling me four times a day, only for me to pick up and no-one be there is not them trying to give me offers. It's them antagonising me. VM are by far the worst for marketing calls out of any company I have been with. They are RELENTLESS. I get calls between 6am to as late as 9pm. It's an actual living hell.
I've reported them to telemarketing standards numerous times now. Nothing has been done about it. I urge people do this anyway. Hopefully something will become of it. Please look this up and report the number, and company calling.
