Poor service

I have a personal loan 37 months personal loan with capitec which I took since 2020/02. All the time I was able to access my loan statement from my banking app, however starting from April to date I cannot access my loan statement and when I call the bank I am been sent from pillar to post and one other thing which is disgusting me it's the higher installment I'm paying but the interest it's like are not decreasing or the balance is not decreasing. I want to see my statement so that I do my own calculations.
