MANGO online South Africa - disgusting customer service

I purchased ladies clothing in April 2019. The clothing arrived but did not fit (clothing not true to size). I requested a return and refund. The document to fill in was emailed straight away and I was asked to place this with the returned items. The courier arrived the next day (17 April 2019). I have not been able to get a response from anyone from Mango regarding my returns and no refund has been paid. The items totalled R2 696. The first email received confirming my request for a return came from Ann Lewis. Even after numerous emails, nothing from them since but they have taken the returns. Without giving a refund, they are the in same category as *******. Really disgusting customer service and a bunch of *******. DO NOT BUY FROM MANGO. I should have read the reviews before I purchased from their online store!
