SPAR2U couldn't satisfy half my order and didn't even have the decency to inform me!!

I order at Spar Kasselvlei via SPAR2U and they couldn't satisfy half my order and now call centre is saying my refund will take over 7 working days to process!! What makes me more angry is that when I tip delivery, it is based on the size of the order and what I deem fair! SO, to find that half of my delivery was not satisfied makes me super angry!! This was a delivery meant for my daughter who stays in a different province than me and I am very disappointed in this service in spoiling what was meant to be a special delivery of goodies to her!
