No response

I have requested multiple times for invoices and statement, and although I do get read receipts, I get no response.

I have emailed 5 times requesting the information, and they haven't responded or provided the requested information/documentation. Its extremely frustrating being ignored and denied the information I am entitled to (yes, I had to pull the entitlement card now).

Is it not required that tax invoices and statement be created and kept? I have never received any invoices and/or statements, and I have been asking for a while now. The way I see it, if you cannot prove that there is an account, why have I paid over the last few years? Who's account have I been paying?

When I called in, apparently there is no record of me...I was a client for years... if there is no record of me, would I then be refunded for the non-existent account that I had been paying?
