PATHETIC CUSTOMER SERVICE!!!

My contract was upgraded in December, I upgraded to an Apple. However in error you continued to debit my account for BIS. <br> <br> On the 30 March I requested for the BIS to be cancelled and requested a refund- no feedback.<br> On the 10 April I called again and requested the same thing. Got a reference S3-8228O-OKN7. No feedback<br> I called in again a few more times and guess what- no damn feedback.<br> <br> Called in again on the 06/05/2015 and 09/05/2015 - asked for the same freaking thing. A refund for the BIS deduction and was told that the money needs to be passed over as a credit and then once approved I will be refunded. Again no feedback. Reference S3-85S1F-FKBVF.<br> I called in today to follow up, I spent 30 minutes on the phone nw, spoke to about 5 people, repeated the story and guess what, your staff are dumb as ***!!!!. No one knows whats going on, eventually the last person I spoke to didn't even assist. He just transferred me to the survey- he cut me off ???? The customer service is pathetic. I want you to give me a report if how many times I called & what was the outcome. I want my refund and feedback within 24 hours. If not the complaint will be escalated further to!!!
