STEER CLEAR of Makro's Online ordering system and Non Exiting Customer Support !

My first (and last) time making the mistake in ordering any product through Makro's Online ordering system. I learned my lesson through ordering and paying for a lawnmower in the middle of May . I received an email more than a week after my EFT indicating that the item is not in stock (although their website indicated an abundance of stock of the item at the time of receiving the payment). The email also informed me that a call agent will contact me to arrange for the EFT refund. I tried contacting the Sales Team Lead (W Matsebele ) on both numbers provided on the mail to lessen the admin burden with a proposal to swap the item out for a different Lawnmower of the same value ...but to no avail. I also responded to the mail in proposing the solution above.... - no response. In the following days I tried phoning the 2 numbers multiple times and even broadened the search criteria to the Makro's national customer care call center - which is even worse as they keep you on hold and disconnect the call after 10 min . Now ,almost 3 weeks later , I am still awaiting either response or refund..... Really disappointing that customer care is not top of mind, but then this instance (like the banking sector) also provides opportunities for similar companies to receive my support in future. Kind regards
