My neighbours were attacked and i couldn’t help because i had no airtime on my phone

My house is located in a corner. And I am a light sleeper. I usually hear thieves trying to break into my neighbours kiosks and doors. I have lived in the area for 4 years now. I have thought about calling the police, but most times I have no airtime on my phone , or the right contacts. One time,I tried to call the Police but i was bounced from one police post to another, being advised to call a different phone number to find the person concerned and i became demotivated.I am lucky, my house has never been robbed but i always hear them in the neighbourhood and i feel so helpless
