Bad customer service and refund policy

I made a purchase on the 23 May 2018. Requested a return on the 25 May, chose a drop off point which didn't work out because the drop off point advised they do not take parcels from customers for spree. Someone collected the package from my residence.

On the 29th of May 2018 my refund was processed. I have made several phone calls and was informed it's still being processed, sent half a dozen emails and that nobody responds to.

I have now run out off options, and have no choice but wait. It's the 18 June 2018 and I still have not received any confirmation or refund.

The website does not state that it takes this long to receive a refund and it's disgusting that customer service cannot provide any assistance other that "it's being processed" or "I will send a email to my manager"
