Poor communication and no response

Dear Marco<br> <br> I have made several attempts to contact you regarding my billing enquiry. I received a message to tell me that my query has been resolved? Huh? How does that work? I did not even get any feedback to what the problem was and why you overcharged me for data useage for 6 months.<br> <br> You have not responsed and after 2 phone calls today to the Autopage call centre, both were unsuccessful.<br> <br> I am extremely annoyed to say the least.<br> <br> Can someone in Autopage who is taking customer service seriously please contact me?<br> <br> Kind Regards<br> Dewalt
