****ED OFF AND FRUSTRATED!!!

I PLACED AN ORDER THROUGH SHEIN AND MY EXPECTED DATE OF DELIVERY WAS BETWEEN 12/10 AND 15/10/2021. WHEN I TRACKED MY SHIPMENT ON 11/10/21, THE LAST UPDATE ON THE SHEIN APP WAS 06/10/21. TUESDAY MORNING 12/10/21, IT WAS STILL NOT UPDATED. I HAD TO CALL IN ON WEDNESDAY 13/10/21 TO TRACK MY PARCEL. I WAS TOLD THAT MY ORDER WILL BE DELIVERED TO ME BETWEEN 14 AND 15/10/21. I DECIDED TO CALL AGAIN NOW TO TRACK MY PARCEL AND I WAS TOLD THAT THERE WAS AN ISSUE AND IT "MIGHT" ONLY BE DELIVERED ON MONDAY 18/10/21. THIS IS EXTREAMLY UNACCAPTABLE. I SHOULD NOT HAVE TO CALL YOU, ITS THE DUTY OF THE COURIER TO CONATCT THEIR CLIENTS OF ANY DELAYS. AND I STILL GET TOLD THAT IT MIGHT BE DELIVERED ON MONDAY. THIS HAS PUT ME IN SUCH A DIFFICULT SITUATION AND THERE IS ABSOLUTLEY NOTHING THAT YOU WILL DO TO SOLVE MY ISSUE. I AM A VERY UNHAPPY CLIENT!!!!!
