airtime taken without any useage

Purchase airtime at 10 am. Sent 1 msg only. could not use the phone because the battery is flat. Charged it and by 2 pm I was out of airtime. Spoke to Vodacom service provider and argued for a long time then spoke to a floor manager and argued and all that happen is they made me feel like a fool. Here are the facts<br> I could not use the phone due to the flat battery.<br> all data was deactivated as I don't use social media.<br> the phone was in my pocket at all times( unlike what they intended that someone else used the phone)<br> I now how to operate this phone and have been using it for years.<br> this is not the fist time airtime when missing<br> calling the call centre is just a waist of time
