Woolworths can't allocate my payment

I paid the balance due as per my statement on my Woolworths credit card as per their instructions and quoted my account number. WFS phoned because they did not receive the payment and I sent the Proof of Payment through immediately. They still have not allocated my payment and now it seems my account is blocked - I use this card for emergencies, so that is fine but I am sure this will affect my credit score which is NOT OKAY! Rectify this IMMEDIATELY.
