Terrible

This is not the first or the second time i am experience such bad service. I have again made payment and asked for a statement so that it can show i have made payment. They send me the statement, but WITH SOMEONE ELSE DETAILS on, i send email to request a new statement, they advise me they made an error on my account. so my STATEMENT is 0.00 up to date but with someone else REFRENCE number, i REALLY don't know what the finance department and invoicing department doing there, cause clearly they don't know what they doing or update, NOTHING is working. I want a statement with my details and also want THE CORRECT statement, and i don't want this every month saying that i don't pay . PLEASE UPDATE YOUR ACCOUNTS and statements!!!!! I am so tired of received emails that i still own you money even though i have paid again for April and May.
