No response on billing request

I requested invoices for my account to be emailed to me as I only received a statement with no breakdown per line, on 17 Sept. A security check was done and confirmed that I will receive my invoices within 24 - 48 hrs. It is now 6 Oct and I have followed up several times, I get absolutely no reply. I think this reflects very bad on your company. Ref nr of all emails sent and call logged with customer services is ***6. I still have all emails in my posession. Urgent please I need urgent feedback as my account t was high and I need breakdown of charges I will supply detail when you contact me. I am still in shock that a supplier can blatantly ignore a customer like this... Appaling service!!
