Waiting on a refund for two weeks now

On the 1st of December 2017 Tia Selvarajh emailed me advising that she received my cancellation of order and that she requested the stock to be returned to the warehouse for a refund and advising that on the 6th of December 2017 I will be refunded. On the 5th of December 2017 the courier company tried to deliver the item to me, I returned the item with the delivery guy and a note and emailed Tia, her reply was that she "tried" to stop the delivery and that "it looks like the couriers did not see her email", and again promised to process the refund. On the 13th of December 2017 once again the courier delivered the item, once again I returned the item with a note and emailed Tia. Her response this time was that she will arrange for the item to be collected from me, when I told her I sent it back as I did before her reply was that she was "trying" to help me. A Customer Service Agent trying to do her JOB! On the 15th of December 2017 the courier company was here to collect an item I did not have all because Tia was "trying" to do her JOB. I emailed Tia and asked for her managers contact details. Hendry Huysamen called me and promised that the refund would be processed, I asked him to keep me updated and he said that he was leaving work at 12pm and would get another manager to call me. This did not happen. on the 18th of December at 11:51am I emailed again asking for feedback, Tia said that she was getting Thomas Khumalo to process the refund. At 2:25pm I asked how long it would take for Thomas to process the refund, I did not receive a response, today at 09:27am I sent another email requesting feedback, Tia made some excuses about the third party courier company and that the funds will be in my account by Friday. I said that I was tired of her excuses and that I wanted the refund processed today. She then said that I cancelled the order while it was out for delivery and this caused the problem – Forgetting that she promised that the funds will be in my account on the 6th of December 2018. I addressed an email to Thomas Khumalo asking him to intervene as I was tired of Tias excuses. Thomas Khumalo did not even bother to reply to my email. Instead Tia emailed Thomas with me CC’d says that paper work was handed over to operations and that he must wait for them to send a credit note. I emailed Tia at 3:25pm asking if operations did what needed to be done and received no reply.

Which has now resulted in me turning to Hello Peter, hopefully I can get a refund processed before Friday this way.
