The store was very busy (as is usually the case in Telstra Shops) but the attitude of the sales guy Ben was great and made it more tolerable. When it was our turn, he greeted us and immediately apologised for the wait in a genuine manner. We needed help for my elderly mother and he was friendly and patient in his explanations and suggestions. He set up Mum's mobile to automatically make her pre paid credits give her the best value for money in future. He also gave Mum some prepaid bonus $ as well. Mum loved it, great goodwill gesture!
We were considering changing service providers, but have now stayed with Telstra.

Approximate cost: $29
