GIVEN THE RUN AROUND!

There payment link that is used for bank transfers does not have another link to send the POP's , messages I get that my parcel is stuck at their warehouse and other sms say that I have not paid customs , even with me sending through the POP to their support email, now I am told that finance hasn't cleared ,but another sms says that it has been cleared and I need to send the POP . ALL JUST A BACK AND FOURTH
