The thing is, this story is going too fast for my liking. And the first few chapters have way to much information. Maybe spread it over the chapters?
Also, I didn't understand the I have no one to talk to. You don't randomly talk to a wrong number, usually.
The fact that they're sharing information like birthday parties to someone they don't know at all, is a little unbelievable too.
And, I didn't get why someone would call a number they knew was wrong.
I've been a bit harsh here, but I'll help you-
i) you could make the first chapter a bit funny, maybe include a pun, so that readers get interested
ii) you could choose a reason for the second call, like maybe prank call or something
iii) spread out the information, build the friendship
