Auto & General Call centre Harassment

Auto &General have hired a call centre that has phone me no less than 20 times in the past 3 weeks

I have told this call centre to take my phone number off thier data base time and time again

Yet they continue to harass me on behalf of auto and general trying to sign me up for insurance I do not require nor desire to take up with them

Stop this or I will be laying a ******** charge of harassment
