Weird phone call

Today a random person called me out of nowhere to invite me to their church? She gave me her supposed name. I asked her where did she get my number and who was she looking for? She responds with "idk" but I would love to invite you it's going to be on Sunday with such and such details she was giving me it was just weird and creepy. Maybe she is part of some cult or something. I said thanks for inviting me but I can't make it. well, you have a good day now.
