INCORRECT CREDIT LISTING

A normal installment was paid on 25 January into my Woolworth's account, however on Transunion (credit bureau) on my profile listing for the month of Jan 2018 it shows unpaid. I contacted the creditor a few times and spoke to different callcenter agents, I was sent a statement confirming I paid and advised to contact the credit bureau myself. Now I'm going back and forth between the two. Woolworth did the mistake, you should update your records that payment was done and on time. This is a inconvenience for me. I need it to be rectified asap.
