Poor service, funds not returned after 10 days

I have been reaching out to Makro who sold me a product that was faulty, smart TV skyworth, have since returned the product, was promised reversal of funds, which i have been waiting for over 10 days as expected. When Im reaching out they simply ignore my emails and calls which has been frustrating. Was told funds would reflect in 10 days which have passed. Makro riverside JHB is *********** and provided a poor customer care. Now I have to run after them, will deactivate my Makro card after this has been settled. Such poor service.
