Terrible service experience. Payment made, No order received.

I'm completely disappointed in the service experience I have received from Sell-SA. I made a purchase for MS Project software on the 14th of September and have emailed through proof of payment 3 times over the past 10 days (including the day the payment was made), and I still have not received my purchase order. I've sent several emails requesting assistance which have been responded to without urgency, yet still no help. I would never recommend any professional or student to purchase software from this company.
