My friend called my phone from an iPhone at the Apple store as a joke, but deleted my number from the phone immediately after. A few days later, I get a call from the same number from this girl who said that my phone was calling her phone multiple times, even though I hadn't been. She called from three different numbers with the same area code and first three digits, and went on to say that I had also texted her. I'm not sure what is going on. What do I do?
