Peter England — I haven't got my item

I order 3 products (shirt, jeans and belt) but I received only 2 items. I did whole payment at one time then why I didn't get all three items at same time? Even though, when I track order now it's showing me cancelled how can it possible? Without my permission how can you cancel it? Also, you didn't give me my money back? How poor service you providing to your customer ! It's been 4 days I'm trying to reach out but I didn't get response from your customer service? Seriously I'm not gonna buy any products from you also I won't recommend to anyone. Such a poor service.
Anyway here is my order details.
Order number :- 4804633
Case number :- CAS-212027-T7V4X0
