Sometimes I REALLY Hate Technology

I seriously blew it today. I had a potential client contact me via email for a consultation and we agreed on a time when I would give them a call. It was a few hours later that I realized I did not have their phone number. As soon as this realization dawned on me, I emailed them back asking for their number. 
No response. 
I emailed again when it was time for the call saying they could call me if they wanted. 
No response.
I wracked my brain to figure out how to contact this person knowing they would think I was just another flakey therapist for missing our phone appointment. 
And it was then that I saw it. 
I had not only the wrong website url (I had it changed from .org to .com a bout 2 months ago), the phone number was WRONG in my email signature. I apparently had a dyslexic moment when creating my signature and switched the numbers.
Oh, so that's why I wasn't getting called back. That's why I was not getting texts from clients.
Dear lord, what had I done? This is my business, and I had sabotaged it before it even got started!
I did what I could to plug some of those holes in the sinking ship that is my private practice. I updated my email signature to the correct web address and phone number. I even wrote instructions on my contact form on this website so people will please give me their phone number so I can call them. 
Technology is supposed to help us be more efficient and productive. But the more I rely on it, the more forgetful I become. I can never seem to remember my schedule. I am constantly checking it throughout the day and I have the constant urge to check it before bedtime, which completely screws up my sleep. 
Because I rely on technology so much, I can't seem to navigate where I am at without my GPS, even if I have driven to certain places over a dozen times. When I was road-tripping my way to Denver I was nearly that person who drove themselves off of a cliff because I lost my GPS signal and neglected the use of my common sense.
So now I am not so patiently waiting for a response from that potential client. I'm pretty sure its a lost cause, but maybe, just maybe they will understand that it was just a mistake and no harm was intended.
Technology is supposed to make our lives simpler and easier, but why does life seem so much more complicated?

UPDATE:
Just in case anyone was wondering, I am now working with that client in addition to many more new clients. Yay!
