MAKRO STILL HAS NOT PAID BACK MY REFUND

on the 14th of May 2019 I ordered 17 Bottles of JC Le Roux online, I could not collect them from the store because of transport problems, i then went to the store (07 June 2019) where i was supposed to collect (Makro Fordsburg) and asked for refund as i did not want the JC Le Roux anymore. i was assisted by a guy named celimpilo who took me to their liquor department for their "manager" Gershwin to authorize the refund. i was told the money will be back into my account in 5-7 days, i have called Makro numerous times and every person i speak to tells me about their finance department that is still to authorize my refund, it is now 2 weeks and no one can assist me i must just wait until their finance department decides to process my refund. can someone please assist
