Frustrated

I have been trying to get Absa Bank for the past 3 years to delete my email address for a Absa Online : Notice of Payment . I get this proof of payment every month & i reply to the email adresses stating its not for me . I get reference number by email & my query will be forwarded to a consultant who will investigate - NOTHING HAPPENS. When i phone i get told i must phone another number or get transferred to another dept. I get pushed around. I went to Absa ( Overport Branch ) during early November 2017 & spoke to the Branch Manager - Nellini Moonilall . I gave her hard copies & she assured me that she will sort this out. Nothing has been done & in Dec 2017 i got another proof of pm email. On the 3 Jan 2018 i phoned Absa on ********** 600 & spoke to Curtis ( explained my problem again ) & was asked to call ********** 123 . Phoned that number & spoke to Fatima & once again was asked to email my query. Will someone at Absa sort this out. Surely it doesnt take over 3yrs to sort a simple query.
