********* Methods - Consumer Act

Hi , I am extremely irritate and wish to understand the logic behind this . Nimble Group has contacted a previous acquaintance of mine , sending them personal details of me and a previous account I have . Is this not ********* to send another person , which I did not consent to , my personal details . I have not been contacted regarding this. No one has sms'd me these details , yet an individual who has nothing to do with me is been giving my account details , balances and authority to make payment arrangement for me . I want to take this further and believe this is extremely unfair . You have no right to do this, and this already puts us on a bad foot with the company . How do you expect a consumer to now build rapport with you? This is extremely unacceptable .
