Makro's Negligence towards customers is gross

Makro has been ignoring me and the last communication in February promised that I should get my refund which has been owing for over three months now, The item was collected no defects but the refund is not coming through and it is tiring having to follow up because they don't even attend to makro care emails, I really don't see why they have that mailbox it serves no purpose at all .As a customer they have lost me in all platforms ,I can never even recommend my family members to do business with Makro.
