lack of feedback and unreasonable answers with no proof

<p>every time i recharge, airtime vanishes and when i call customer service, they say it is internet which i did not even use... they have no proof of any internet usage but refer to the system. i recharge and then unable to call as i get that man talking telling me i do not have airtime whilst i do and when i check, gone boys, call centre provides bad attitude services. it happend last year and still didnt receive feedback and it happens now, no reasonable answers, even lazy to waste my effort calling them as i know what they will say already. please assist</p>
