Edgars call Centre poor service and don't care attitude

I submitted a query on some mobile content fee and the reference number thereof is ********** 0333/GO. Among others, I had requested that this so called airtime subscription whose airtime I don't even receive, be canceled and refunded. This morning I called the call Centre. After about two minutes my call was attended to. However, later I was made to hold for 5-6 minutes. Then my call was terminated. In spite of the fact that I had submitted my reference number, no one has bothered to call me back. This is how much big retailers handle us once their stomachs are full with our monies. It is pathetic and unacceptable. I have to state that two days ago I received and sms stating that a subscription was canceled, but because the sms was not signed, I am still left to guess as to who could've sent it to me. Again it doesn't say anything about a refund. So angazi!!!
