Bad reflwction

I took a personal loan out with standard bank about a year ago. I app**** for a home loan recently and was rejected due to standard bank loan being in arrears or/ and late payments. I signed a debit order when taking this loan so ud ur us late then I am not to blame. The only time I am aware that there may be a non payment was when covid started and I was granted permission. Whether standard bank deducted this or not I am not aware of as I do not get statements even though I requested this at the menlyn branch. I am very upset. I called standard bank and they are now insisting I go unto the branch and won't send me a statement. I lost this home opportunity because of this. If I was in arrears or late why then was I not notified.
