So much for " how can we help you"

It is incredibly upsetting that FNB rejects some of my debit orders and when I request for my bank statement to prove to the other company that I made a payment... They tell me they cannot help me and I'll have to wait till they send it on the said date which I never even agreed to. I never agreed to have my bank statements sent quarterly but didn't mind because for years I've been paying via direct debit amd never skipped a payment and when I need help... They can't! So much for how can we help you right. I was placed on hold for over 5 minutes while waiting to be put through to yet another department that would change when I receive my bank statement. I pathetic. Tell me FNB... What do I do now to have my services in suspended by this company since you're not willing to help?
