Dear Mr Penn,
While you're in a spending mood, how about looking into mobile phone Black Spots or holes. You mentioned nothing about this.
I live about 1km from Highway 1 in suburban Brisbane and still have to walk around the house to find a mobile signal. The last time I complained to your (offshore) customer service folk, I was told it was because all the traffic on the highway was using all the available bandwidth.
OK, at peak times it's pretty busy, but at 2am?
BTW, you're not alone. Optus mobile is garbage here, too.
