No loyalty towards life long clients,

I recently saw on the internet that some savings accounts can earn an additional 0.25% interest If opened and managed digitally. I have a Depositor Plus account and phoned Absa to enquire as to the reason why I'm not getting the higher interest rate. I was subsequently informed it was because I opened my account in 2017. I am very unhappy that life long customers are getting a worse rate that new customers. I was then told I could open another Depositor plus account, transfer the money and close the old account to to qualify for the higher rate. I asked if it was not possible to just adjust the rate on my account, but was told it's not possible. Really Absa??? I keep on threatening and threatening to close all my accounts with Absa, but I really should just bite the bullet and do it.
