Extreme delay in order delivery and terrible service

I ordered things from Cotton On over 3 weeks ago and I have still not received my order, On top of the delay, when I contacted DPD to track my parcel, as there were no updates on their website, they first told me that they already delivered my parcel then they said they did not but my address on their side might be incorrect, both of which were lies! As I was making no progress with getting information regarding my parcel from DP, I contacted Cotton On directly. They however did not give me any clear answers at first, and the one customer service agent with whom I spoke was quite rude. Needless to say, I am very frustrated and disappointed in the terrible service I have received from both Cotton On and DPD, not only is my parcel extremely late but I also had to make contact with them, wasting my airtime and data, when communicating should have been made from Cotton On/DPD. Additionally, my family member who ordered a parcel (the 2nd of December 2023) received theirs within a few days, but I have not gotten mine. Again, I am utterly disgusted at this poor service Terrible service!
