Not receiving account

For the past 5 month I have to phone in to get my account and statement emailed to me. I have 3 devices.First they told me it is a problem with my email. Then I receive one invoice but no summery.<br> But when I phone in they send it to me and there is no problem with my email.<br> Two month ago they admitted that there was a problem on their site and it has been resolved. Last month only one invoice again. I phone again and was told it has gone up to management and a Manager is gone phone me. Still waiting!!!<br> Today again one invoice only. So I phone again and after checking the consultant told me the other numbers where not activated to send out via email. <br> I ask her to please send me the missing two and the summery. What comes ?.....only the summery.<br> Don't they understand English??????<br> Hello ...after 4 month me calling in and no one can pick this up. What *********** staff have you got working for you???<br> I pay by EFT so make sure you send out your invoices or is this the customers job to phone for the invoice in order to pay?????
