Incorrect Billing Information

Seems I have to beg them to get my account details in order which is forever incorrect.My monthly amount to be which should be same every month is forever incoŕrect and when I phone in, I get different amounts as my calls will go to different agent each time and logging a query/complain online ,turnaround time stated is never ever met and email response even worse.Additional I have 3 insured decoders & last month they send me email of my insurance being in arrears after disputing that ,they apologized & confirmed insurance up to date.Current month ,caller agent/s inform me only 2 of my 3 decoders insured and again dispute that as I have never taken any off insurance and my monthly amount to pay mysteriously doubled up and again send a dispute on these 2 issues and turnaround time for response not met and still pending with no resolution in sight & due date for payment in 24hrs.Customer No ***0 & would like this escalated to Ombud as I cannot allow this breach of extreme proportions go unchallenged
