Disastrous return and horrible service

I ordered items from superbalist on 25 March 2018, received the order on 29/05/2018. One of the items did not fit me, so I logged a return for exchange same day, which was scheduled to be collected on 03/04/2018. On 10/04/2018 I received an email from Insaaf Williams to reschedule because the courier company said they could not get hold of me, days later the courier called and we arranged that they must collect at my workplace but they never came. On 14/04/2018 Lerato Stevens sent me an email to say they was a miscommunication and the courier says they never delivered my items to start with so they cancelled my return. I then advised that I did receive the items and I was told to lodge another return. The item was eventually collected, before I could lodge another return. I then lodged the return for refund this time, coz I was already frustrated!!

I never received my refund in my wallet, when I call they say they never received my return and I should send proof of collection which the courier did not give me!! And never thought it was important since I have never encountered such with Spree!

Anyway I was told that they are investigating the matter, its been a week and no one is saying anything! How hard is it to track the courier company that was assigned to collect? Superbalist I want my hard earned money please!
