No customer detail privacy at Ackermans

I have been struggling to Ackermans to delete my contact number from their system as i don't have an account with them and i am not Keitumetse Huma. I provided them with my ID went to Facebook to complain. Told my query will be resolved, spoke to Elsonia Pretorius of customer escalations till even today my number is not deleted. I am getting these stupid updates about account in arrears, statements special updates almost everyday.

Ackermans doesn't care about its customers information as if they cared they would have deleted my number immediately after i explained and showed them proof that i don't have an account with them instead am getting this lady's statements. How do you protect your customers privacy by constantly sending their statements to someone else even after being notified that it's the wrong person.
