Invoice to pay lost goods

I have continually request an invoice for my account from home choice (for the past three month) but to date I have not received anything.<br> <br> I have spoken to a number of people there requesting this invoice including one of your supervisors Maruwaan but I have received no help.<br> <br> Home choice continues to list me as a bad payer even though I have made countless efforts to try and resolve this problem which was initially cause by home choice failing to deliver me the goods I had ordered.<br> Without am invoice the Post Office cannot pay for the good which were misplaced.<br> <br> Please could you kindly email me an invoice so that the Post Office can pay for the goods. Can Home Choice please do their job and send me my invoice already.
