Tax duties

I'm feeling very frustrated because although I have sent them proof of payment already 4 days ago for a payment made to them using the peach payments portal sent to me on their behalf, my tracking status still has not been updated and still states that I have not paid. I'm very disappointed at Skynet. I called them every times around 2pm on Friday, kept getting put in the queue and then calls disconnected. If I never use Skynet again, it will be too soon.
