No Invoice ever available

Every month I have to either log a request or phone you guys to get a copy of my invoice - I NEED this in order to claim for my Cellphone Allowance and would expect you to be able to automate this so that I do not have to continually ask!!!!!! <br> <br> According to your extremely badly developed portal I should have access to an online invoice as I pay for My.Account Pro (see the tooltip around this service if you don't believe me). As far as I am aware, I am entitled to an Invoice AS WELL as an Itemised bill as part of your Service Contract, yet I do not receive both of these. WHY NOT? Is this not a breach of contract on your behalf?<br> <br> Please send me my latest invoices for the last 2 months so that I can put in a claim for my Cellphone allowance at my company - this is now costing me money... <br>
