No feedback from customer care

I ordered clothes in Dec 2017 - wrong parcel was delivered on 2 Jan 2018. Upon return request another incorrect parcel was delivered on 12 Jan 2018. I contacted spree via email sent to their customer care service - only to receive an automatic reply but no further assistance on 2 Jan 2018 and again on 9 Jan 2018. Then on 12 Jan 2018 I received an incorrect parcel again (which was supposed to be the order from Dec 2017) - however, I can not return the item as the app doesn't allow me to request a return as the item was apparently not ordered/delivered. I complained on spree.co.za (Facebook page) on 12 Jan 2018 and again on 14 Jan 2018 - STILL NO RESPONSE!!!! I am a regular spree user and have never had an issue - but I have been struggling for 3 weeks to get a reply from customer service. No one even contacted me - I want a full refund and I WILL NEVER ORDER FROM SPREE AGAIN if this is how they treat regular customers.
