WRONG CELL PHONE - After reporting - ongoing

Hallo I keep on getting sms that I have to pay my account or they will take further action. I never had an Woolworths account. I do not have any accounts for clothing... I phone and ask them to remove my number from their system... without success. PLEASE PLEASE ... This number is my number for more than six years<br> I do not appreciate getting sms all hours of the day.
