Unreliable, poor customer service

I ordered 3 items from spree.co.za on the 9th February 2018, on the 19th February 2018 I went to collect them only to find out I only received 1 item, I called them the same time and they said the other box will arrive during the week, I sent the email the same day, Friday the 23rd February 2018 I called them again and they said they'll talk to pargo services and ask how far is my delivery they'll get back to me, and they didn't get back to me. On the 7th March 2018 I called them again and they told me they'll to pargo services. They called later that telling me that my parcel is lost, do I want a refund or place another order, I told to refund me, and they said they'll call me the following day... Saturday the 10th March 2018 I called them and told them I haven't received my refund, they said it's in a queue to be processed. Till today the 14th March 2018 I'm still waiting for my refund
