Worst Service from a Complaints department

I recently app**** for an RCP and was approved and then realised that the address on the contract is incorrect. I then contacted STD bank and was transferred from Pillar to post almost 7 times and was informed by the agent that he can see a lot of addresses on my profile and i requested who changed my address and how it was possible since i never provided any details. he could not advise me who changed it and transferred me to complaints, spoke t o lady who was very rude and wanted to speak louder then me, and had more attitude. STD bank is at fault here by changing my address without my knowledge and consent, hence my personal information was sent to an unknown address which contravenes the POPI act. i am definitely taking the matter to the ombudsman as i have wasted my time and money to sort out the matter and yet i do not even know if it was sorted. plus who else has my personal information now. I want to be compensated as for the time, money and the fact that i paid for statements i did not even received for the past 2-3 months but did not really notice.
