My relatives introduced me to an object. I haven't met her yet, but I gave her my phone number and mobile phone number. I want to send her a message first.

Call directly and ask who you are, and explain who introduced you two. Who are you? Don't be shy. Since it's an introduction. Everyone knows it's to meet. Just find a cold drink bar or coffee shop with a better environment and go out to meet and talk. Don't be stingy. hope this helps
