Dreadful cold callers will not leave us alone. Having blocked 2 of there numbers they still get through using other phone lines 3 or 4 times a day, everyday for as long as i can remember, regardless of what we say or how many times we ask them to stop. Would you trust a company that harasses people? I know I wouldn't. would have 0 stars if possible
