I'd rather know about not being able to get to the back of someone's house BEFORE I get there rather than finding out I had wasted my time getting there.
Yes I do get some saying 'not this time' but some of the properties we do are out in the sticks and wasting the time travelling when I could be earning would be worse than the odd one delaying the job.
It's all part of the customer service for me, my customers knowing they can get in touch is a big part of that.
Horses for courses.
Anyway, the thread was about text services and I was just offering an alternative.
