Nobody can help me at Makro, it's hilarious

You know I've been busy with this order for almost a month now, the order wasn't delivered, I made another plan and now Makro can't get the order cancelled with the seller. I'm honestly exhausted with the trouble of just wanting to cancel and get my money back I've been calling since the 4th June everyday waiting 10-20min to get through and to ask my cancel my order everyday I get the same response seller is not responding to makro emails. Then I get an email saying they will deliver it's like makro is torturing me, like I want to cry how bad can this experience get. Makro online has no proper measures inplace to handle online orders - why torture your clients get your foundation right before you open online and cancel my order and get me my money back.
