I think it's due to your incompetency because every other network treat it as a free number. Otherwise you should have call it for proper investigation. Is a free conference call number.
Thanks for your response, however I have call that same number from another mobile number an I wasn't charged you could also call it with a different number.
Hi, I called this number 0906464160 which is a free service number and I have been charged from my land line credit. Could you please return my land line credit as this number is free till 59th minute. Thanks.
