Babies r us employee stalker (long)

So I went to babies r us the other day with my hubby and I applied for the credit card and the cashier (male) was super friendly with us especially me even in front of my SO.. I took it as he just has an outgoing personality and was trying to give good customer service. He asked what we were having and when we were due, I said girl, April 17th... I got approved for it and we shopped around and came back to buy some items with the 15%. We left that night and I went back another day with my cousin, she has a 10m old and she wanted to buy him some cute pjs that were 75% off. It was just me and my cousin and he goes to me "girl right?" Like asking if I was carrying a girl and I was like "ha yes you remembered" didn't think anything of it.. I went home and the next morning I got a phone call in the morning around 7am.. it sounded just like this man and he said "hey it's jorge.. you gave me your number.." I was really confused. I've been with my SO for 5 years and no guy has my # I ran to my SO and put the man on speaker and my SO was telling me what to ask.. "where did I give you my number ?" He said "Idk" and then I asked "how do I look?" He said "you have a beautiful smile and long hair" His voice sounded exactly like that guys from babies r us (it's a distinct voice idk how to explain) and so my hubby told him to fuck off but we still weren't sure who it was. So today I go back cause I needed some things and i went to go pay with another cashier and he kept looking at me :( even my cousin felt it and was freaked out. I think he got my info from my rewards or from the day I applied for the credit card.. SUPER scary and weird you guys. I just wanted to share my story bc i honestly feel scared, if someone takes your number in that way why won't they take your address.. always becareful. (Btw I'm 32 weeks) this guy clearly has some sort of fetish? So weird :(
