Makro has terrible service

I ordered from Makro on the 31st of March few items and added a special instruction for them to deliver my order together with a Fridge and Washing machine i had bought from them, they failed to do that, i have been following on my order on their WhatsApp line and it shows my order was picked up on the 31st yet no one had contacted me, i also phoned their contact centre on Tuesday following up on my order i was told that they attempted to call me and i wasn't available, asked what number they had and i was given an incorrect number, i gave my correct cell number to their contact centre person and requested for Thursday delivery as i was going to work from home, still that wasn't done, Friday i phoned them again and i was given same excuse that they cannot get hold of me, and when i asked that they deliver to my work address i was told that couldn't be done. I work for logistics company and was amazed that a change of address could be used as a ridiculous excuse.. tried calling them again today held for 13 minutes and their line was not answered, to say i am disappointed is an understatement, i am disgusted at the ridiculous service they offer and the bare minimum they go through to try resolve matters, worse their KPI is at 7 working days.. I have been without a microwave for over a week and now i have to wait another 10 working days for them to refund me... regret spending +/- 20 000 with them this month alone, they don't deserve a cent and i will not be spending my hard earned money with you Makro anymore, your competitors have gained a client thanks to your ridiculous service
