Delay delivery

Paxi customer servise is the worst as i have been enquiring about my parcel which is supposed to be delivered on the after 7 days from the 11th of September, I urgently need the parcel and now I’m told about the 25th of September, which is unacceptable my delivery date is supposed to be the 19th I called them asking if I can collect my parcel wherever it is or pay extra fee for the delivery. I was told there’s nothing they can do and they refused when I asked to speak to the manager .I’m getting different dates and this is frustrating the parcel has been with the courier since the 11th. No update since then.
