Poor Poor Poor Services!!!!

I placed an online order on the 28th of March and received my i=order confirmation, paid the full amount and used my order number as reference, as indicated on the order confirmation email. Days later I call Hifi to ascertain when my order will be delivered and i'm told the coming Friday which is the 6th of April. On the date of expected delivery I call Hifi and i'm told my order has been cancelled because payment was not made.

This is absolutely frustrating to me because I made the payment and used a correct a reference to simplify the allocation process for their accounts department. I was not informed I need to send through a proof of payment. Now I need to consistently follow up with the manager Yushra Abrahams who can not tell me precisely when my order will be delivered!!
