Over two weeks and still no refund

I returned a pair of Sunglasses to the store in Nelson Mandela square on the 5th of April. I was told that they could not refund me in store and that the refund would be paid directly into my account within 5 working days, even though the money had already been deducted from my account. Over two weeks have passed and still I have not received my refund. I have sent emails to [Email Removed] but not a single response. I have also left voice messages on the number provided on their website for refunds and yet no one calls back. I am shocked that a company of this size has such pathetic processes and even worse customer service. I demand to know when MY money will be given back to me!
