Horrible customer service

Poor customer service regarding payment of a refund. I bought a TV online from Makro and requested a return on 8 March 2024. Makro acknowledged the return and arranged for collection of the TV which took place on 19 March 2024. Since then, I have been following up via email and telephone to enquire about my refund of R12,999.00, but until today I am still waiting to be refunded. I don't get any feedback from Makro regarding the progress and every time I call their call centre, all I am told is that the matter will be escalated. This is horrible customer service.
