I called and I didn't have airtime

I called and I didn't have airtime. Pieter Kruger answered my call and called me back. He was fast and efficient as I was stuck on the freeway. He arranged a tow truck and called again to make sure that the truck arrived. I told him that he does not have to call again because I'm not far from home and I was safe. Guess what.... He called to make sure that I'm home safe. Excellent service. I'm impressed.
