Pick n Pay Online debacle

I endeavoured to place an order with PnP Online on 2nd June, but the system prevented me from receiving delivery confirmation. An amount of R2099.63 was, however, deducted from my credit card. Frequent telephonic contacts from 3rd June and subsequent days have met with apologies due to a system change (courier delivery cancelled and reduction in the maximum size of order) and "escalation to supervisor". 5 days later, and I have not received my order, nor have I received a refund of my money. This is unacceptable, and email contact has also reached a dead end. All I want is a refund, a system glitch is not my problem!
