I need help with technology...?

So my friend was chatting someone on omegle and he gave her his number. We thought it would be funny to call it on prankdial.com. So if you dont know what it is it has fake conversations and lets you call anyone you want and you put in any number you want as the place thats caalling it. Well my friend acidently put it my number. The person texted me... I've been freaking out that they might be like a creep and they track me down. Ok so I have a Verizon iPhone and I deleted the number off my phone. Should I be ok? Please don't say anything mean. Thanks.
