Hang in there......it is true that if they call and you don't answer the phone you will lose your spot n the queue.

All I can say is make sure you can answer your phone at all times.

With regards to them not turning up for an appointment, I have not experienced this. I have has two internet connections done within the last three months and on both occasions they came after calling me.

If you do call 115, be patient and polite, remember these people are working for someone who tells them what to do, they are not the ones in control.
