When I first started providing, I had an NCNS as well with a gentlemen. He was upset and posted a thread as well.
NCNS's are a loss of time and money on both ends. I've learned from my mistakes and improved my communication skills as well. Always have a line of communication open. Yes, life does happen, but unless you have died, at least try to make an attempt to communicate back.
Nonetheless, if that gentleman ever decided to book another date with me, I would offer a generous discount to make up for the time and money lost and give him the best BJ ever to make up for any misunderstandings!
You are pretty new to providing. Just learn from this and aspire to never let this happen again and you'll be fine.
