I thought I sent it! Fort Wayne computer repair

Last week a new computer client texted me they were ready for a service call to set up a new computer.  The last detail was when to visit.  We texted back and forth to get a mutual agreeable time and I sent my last text to confirm when I would arrive.  It was odd that I never heard back from them after three days.  The message history was still in my smartphone and the day I was going to visit I went to text that I needed the address.  To my horror I realized the last message of mine never got sent!  No wonder they never replied.  I thought I had sent it.  I’ll be more careful next time
