Xpressbees Logistics — delivery cancelled without informing

I had a delivery (Order no. Gshm6700y000n5a) from shein.in which was to be done by xpressbees with order tracking id [protected]. The delivery guy contacted me on 6th of may when i requested future delivery. Then on 15th and 18th may the delivery was rescheduled and both of which was cancelled by the delivery person without contacting me. Now my order is returning back to the warehouse. Because of miscommunication from some stupid delivery guy, i'm suffering. Now when i call shein for the same, they ask to consult the logistics and on asking the logistics they ask me to contact shein. They certainly do not respect their customers.
