pathetic service

Firstly, I never get my itimized billing and invoice unless I request for it and i clearly stipulated that they should be sent to me via email every month. This month was the worse ever, I mean it's over 3 weeks now requesting for the same thing ( itimized billing and tax invoice) still have not received it, i called the call centre and the call centre agent gave me attitude and still sent me the wrong things. Called in again after 2 to 3days and they still sent me the wrong stuffs and they told me they escalated the matter.... But still nothing. Sent an email to that business email address and they too sent me the wrong stuffs. Sent another email this morning expressing my frustration and how urgently I need my itimized billing and tax invoice and no response yet... Its time to move networks!!! i have a very busy life than to sit and deal with this nonsense every month
