Absa Bad interest rate offers when raising a homeloan bond and Absa does not value their clients

Absa homeloan is a **** I decided to raise my bond amount to my suprise Absa is offering me a ridiculous interest rate 12,19 higher than the current prime rate while my current interest is 11,11 on my bond When I ask how do they justify the interest they providing me with , because I have been paying them so well and paying extra on my homeloan plus my credit score is good they still can’t answer me.Absa it’s taking advantage of it’s client .For the fact that I have to go to another bank it shows that they don’t value their clients.I regret taking a homeloan with them .To my suprise I declined the interest rate they offering only for them to send my application to the attorneys without confirming with me .C-***0
