MBD stop calling and sending me Sms. You have the wrong person. ID number confirm this

Stop harrasing me. I've already confirmed with you on numerous occasions that I have no idea what you want money for and also your agent keeps on telling me the ID number I provide is incorrect. Maybe you should look at the fact that the ID number Im providing is the correct ID and that you have the wrong person. Im receiving these msgs several times per day and phone calls. Please remove my details from your system with emidiate effect. See below msgs of harrastment received from MBD. We have not received pmt on your NHLS acc. Pls make immediate pmt and call MBD on (011) ********** to set up a debit order. Ref: ********** ********** 34
