im not sure what your point is? its reasonably common these days to have a long hold time, and compared to others 29 mins is actually a short time.
there could be any number of reasons why its so long
Is it? Maybe for voda and slingshot but most providers it's far better
spark slingshot and vodafone have a large holding in the broadband market and they all have long wait times. for a lot of smaller providers its likely to be better.
it also depends on when you ring, is there a major outage and everyone is rining? is it lunchtime, end of work etc they all contribute to when call times could be longer
You read like a professional apologista....
