****ed Off

I bought a pair of shoes online on the 20th November. I was charged a R100 extra for delivery fees yet the first online delivery is free. they revered the R100 on the 28th November. I kept on phoning them to ask when will my order be delivered they kept on telling me they waiting on the couriers to collect on from the date of purchase the delivery time is 7 working days. Today i contacted Street Fever just to be told the couriers collected the order last week and that I can contact them to track the order. I contacted the couriers and was told that they cant pick up the weigh bill number on their system. Please tell me who is lying because this is the worst experience ever.
