Process my refund

I purchased 2 jackets from cape union mart's on-line store in November 2014 as I was travelling abroad in Dec of the same year. Shaun the sales person assisted me and was prompt in his service. I however returned from the UK not having worn either jacket. I then called Shaun when I returned to work if I could get a refund for those jackets seeing I haven't worn them and all tags were still in place. He said yes and was so kind to send the courier to collect the jackets from me. The jackets was sent back via Ram couriers (RW***3 - waybill #) on the 29/01/2015. To date I have not received my refund from the on-line store which amounts to R1198, now me being in retail myself I understand red tape and procedures but 20 days later, inconveniencing the customer is a bit much, I've spoken to various people at on-line sales, Zainab and Zina, who never calls me back with the exception of once. I've been calling every day for 15 days straight and nothing, I got an explanation that a 3rd party handles refunds, but seriously that cannot be my problem to sort out. I would like the money owing to me no later than Monday 23rd Feb 15. Can somebody plse sort this out as a matter of urgency.
