I last had a contract with this company approx 10 years ago. Twelve months ago they started calling my mobile number almost daily trying to get my business, despite me asking them to stop doing this. They now call me twice a day, how can these people be STOPPED!!!
Response to the initial reply from Three: -
I followed the link provided and was informed by the Three chat representative that they were unable to stop the cold calls from their sales team. The representative suggested that I contact my current mobile provider and ask if they could block the cold calls from Three. Seems like a strange business that relies on other companies to control their sales force.
