I have been a loyal customer with Telstra mobile for over 12 years. In this time i have experienced a fair few issues. The biggest issue I have had was when they all of a sudden took me off my $79 cap (which gave me a significant number of phone calls) and i had been using comfortably for 3 months and placed me on a $30 plan in error. After receiving an exceptionally large phone bill, and realising my plan had changed i tried to fix the issue, only to find the next month I had another large bill and a late fee for the remianing amount. This continued to happen month after month and was never fixed. I spent an hour a week for 4 or 5 months in a testra shop and another hour on the phone with them trying to sort out the issue. In this time my phone bill escalated to almost $10, 000, my phone was cut off several times, which meant heading to a pay phone to try and have it reconnected. The issue was finally resolved, however in more recent times i have now found myself to be continually upgrading to higher plans, as my phone bill continues to rise each month. Just recently after keeping to my cap for several months in a row i received a phone bill hundreds of dollars over what i was previously spending. Telstra had changed there call rate, and as my bills are sent to me via email i was never notified of this change. The business has given me nothing but trouble and a very low bank balance.
