Reporting that payments has not been made

Woolworth's a has reported to the credit beta that I am not paying my accounts. After this came to my attention I contacted Woolworth's finance department and sent them the proof of payment approx 2 weeks ago. According to to Woolworth's my accounts is up to date however when a app**** for credit today they informed me that I still don't qualify. This is due to Woolworth's still!!!!!
