Sent and resent proof of payment more than 4 times

Dinah, your latest request of proof of payment refers dated 6 April 2016. I resent proof of payment for the umpteenth time on the same date and no courtesy reply from you nor colleagues to confirm. <br> <br> IT maybe blocking attachments? With a little initiative, you or colleagues could ask and check this from your IT, especially seeing this complaint runs from the 14th March 2016. In your place, I would do everything to try and fix things myself and make this convenient as possible for my client. Yet here, it is not so - you'd rather keep asking for proof of payment, I keep sending it and you should by now check why this is not working instead of asking again<br> <br> Also seeing this runs for almost a month, instead of bombarding your client with admin and wasting time, why not ask your finance department to do a forensic audit of this account (as opposed to accepting what you see on your screen where there is an obvious fault in your systems). I know \forensic audit\" may sound intimidating to you, but it should not take your finance more than 30mins assuming they know what they're doing. This has the advantage of saving you time and grief, but most important, it stops wasting your clients time"
