Payment not reflecting

I made a payment last week Monday and I have been uploading my POP multiple times on the link provided. May I please get urgent assistance? I need my parcel delivered urgently. From last week Monday I am being told that Finance is processing the POP. This is really unfair especially when I have paid on time using the options provided in your links, if the online payment option has an issue on your side why do I have to suffer as the customer? I've been calling almost everyday and every urgent is telling me about 48 hours, how many 48 hours should I wait for? This is really frustrating
