Makro | Worst Customer Service EVER

Bought items at Makro Online on 1 October 2023 for which I were charged for incorrectly. Contacted Customer Service the same day regarding the overcharge. Someone from Customer Service phoned me that Saturday, 21 October 2023 to find out if I was assisted in this matter on which I rep**** "not yet". They then mentioned that the query will be escalated. On 26 October 2023 I followed up again as nobody came back to me yet, and again on 28 October 2023. 31 October 2023 I received a email stating "Good day, The store will return & ring, the difference the customer was overcharged, will be refunded back to the customer account used to pay for the order. Funds will reflect within 3-7 working days." After the 7th Working Day (9 November 2023) I followed up again as I received no refund as yet with no response from Makro. I tried again on 13 November 2023 and 16 November 2023 with no response from Makro. They are just ignoring correspondence now and already waiting 14 Working Days for the refund to reflect in my bank account as promised by Makro and more than a month since the initial purchase. Worst Customer Service ever.
