Apathetic feedback and lack of response

I logged a complaint last week. I received one call promising to get to the bottom of the issue .<br> <br> I requested that I be emailed as I am unable to take any more calls during working hours. This is because I sit for sometimes up to an hour and over waiting for someone in Sales to pick up. The Manager does not even respond to my emails.<br> <br> Now my payment on my new contract ios wrong too.<br> <br> I app**** for a Tablet now a month ago - no response to emails and no feedback from complaints line<br> <br> I have also had no feed back from the complaints lines - it would be funny if it wasnt do frustrating
