Will Not Stop Sending me Messages

They registered my number as an account holder, I no longer work there, I have called them multiple times to remove my number from their database as I am not the account holder but they deny having it in their system. However, every month on the 20th they keep sending me reminders of payment to be made. Its really irritating having to keep receiving such messages.<br> <br> SUPPLIER'S RESPONSE Neotel Time and Date 09:51:30 | Fri 29 Jan 16<br> Hello Suregirl,<br> <br> Thank you for notifying us.
