70 charges over 2 phone bills - these call coincide with nuisance calls from overseas telemarketers according to Telstra this is a reverse charge which was accepted - absolutely not true - on further enquiry - apparently if you answer the call you automatically cop this charge?? You would need a phone with call number display to know NOT to answer it - AND Telstra charges $6 per qtr to activate. Alternatively you have to change your number and make it a silent no. because a single National no. cannot be barred/blocked. Nor can a single international no. Is this a win win for Telstra?
