Makro - Worst service ever

I ordered a lounge sweat with "free delivery" on the 3rd of August, immediately after my order was processed the same day I realised that my delivery address was wrong (even though I changed it on my profile) Since then I have been send WA's, emails and phoning to try and get my adress changed and in the meantime I get "congratulation your order will be delivered" emails. Today the Makro agent said I should phone the courier company directly which I did and was informed that they can't help me and that I should just collect it myself - REALLY?? Makro is still not helping and every agent have a different promise.. How do I get my furniture?? This is so the last time I'm buying anything from Makro...
