Parcel not delivered

Been waiting for my parcel since the 29th February. the tracking update status has been saying "in dispatch" since the 08th of march 2024 and has never changed ever again. Been sending Buffalo several messages on WhatsApp but they stopped replying to my messages. I call them almost everyday and they give me different stories. either they say they have escalated the matter, the other one said my parcel was misplaced and it will be delivered within 72 hours but 72 hours has passed long ago and I am still waiting. I did pay rates and taxes on the 29th February 2024. Now they no longer answer my calls or replay to my WhatsApp messages.
