Bad service, rude client service agents

I'm not happy with their service, my order was approved from Temu and confirmed then buffalo sent me their link to pay for custom fee, since then I have been updated once about my order that the flight is departing, now today I'm calling buffalo logistics and raising my concerns, they are now telling me my order is still in China, how come,it's over five working days now, worse part they are rude, using their 7-14 working days policy to protect themselves, i wish Temu would give us options to chose our logistics company, cause buffalo is worse
