Changing info on my account without my authorisation

<p>Please tell me why my address has changed and who authorised the change. On 1 June 2017 it will be 5 years that I have stayed and owned this property at this address. An address which is bonded through Standard bank. Refer to Homeloan Account number ********** 00 as reference. For the last almost 5 years my address has been that address. The same address I have received statements. Up and till 13 January 2017 my address was still correct then it all of a sudden as per your statements that you mail me changed to another address…an address I have not lived in for more than 5 years. Please kindly explain WHY? IMMEDIATELY correct this and advise who authorised such a change. I WANT TO KNOW WHO IN STANDARD BANK CHANGED THIS WITHOUT MY PERMISSION! This is unacceptable that changes can just be authorised without permission. What type of Mickey mouse organisation am I dealing with. This is not my first complaint and it looks like Standard banks service norm. I would like an explanation. Kindly correct this and advise once done with proof by means of a ref# that it has been done. Honestly my trust in Standard bank is getting less and less by the day.</p> <p> </p>
