I received a call from a number [protected] inquiring about my order whether i received or not. He said i had won some lucky draw and will get a car. I understood it is a fraud but my concern is how did that person know that i had ordered from shop-clues on that date. This is serious issue where customer data is leaked and is not safe.

Shop-clues must take this issue seriously. I just saw many other complaints like this just now. Th issue is marked as resolved but then how does it keep repeating like this.
Not protecting customer data is a serious offence.
