Parcel marked as delivered but not received : BUFZA8VD08619RVYQ

Buffalo logistics is the worst delivery ever, i ordered from shein and they say my parcel has been delivered meanwhile it was not. I tried contacting them countless times and this issue is not getting resolved, the only thing i hear is that we are still waiting for feedback from the driver, from last week Tuesday till this Wednesday the update is the same(we are still waiting for feedback from driver) why would the driver have the whole week plus to provide feedback? I am being taken for a ride here actually because i am the clown in this situation. Christina contacted me on Friday morning, today she still has the same feedback as last week meaning my query is not being taken into consideration (we are still waiting for feedback from drivers manager and christina will contact you back everyday). This is nonsense
