Uniform. Need it Won't Get It

 I ordered my uniform at the interview. I picked sizes I usually wear. Went to induction to find trousers don't fit. I ordered the next size up. Every time a uniform order came into store I'd go to HR asking if my uniform was in? Nope. I worked there for FOUR MONTHS and never got those trousers. I had to go and buy my own. No compensation for that. No apology. But they continued to tell me, you are supposed to wear Sainsburys trousers. Oh but how? The order is NEVER there! How can it take MONTHS for a pair of trousers to turn up?
