4 days to get an invoice generated after 4 telephone calls

<p>Why do I as the customer have to call you 4 times (I returned your vehicle on Sunday 23rd Jul, and I called on Monday 24th, Tuesday 25th and twice on Wednesday 26th) to get an invoice generated. When I called for the second time on Wednesday 26th (at 11h29) I was told that the invoice had been generated but for whatever reason it takes 24 hours to synchronise, that my deposit was still being held until, and I quote, "however long your bank takes to process it". In this day and age of electronic invoicing that is ABYSMAL customer service in my book. You are holding my deposit for an unnecessarily long amount of time!</p>
