See who's calling

Callers number 02394318000. Move away from current mobile phone provider. The caller wanted me to change my mobile phone provider as I could have good benefits. I said No. He continued, From the beginning. I said I was not interested, Please remove my details from your database. He said he could only do that by going through his process and was about to ask me for my personal details. I said no, You have my telephone number that is all you need to remove the details. He repeated the cycle.
