Makro Messes up Cancer Patient's last birthday

I ordered a Sewing machine for my wife's birthday, last week and when the parcel arrived, and I opened it .... it was a smart pulse 12v charger. My wife is a stage 4 cancer patient that has lympnode, liver, pancreas and lung cancer. This is her last birthday with us. And wanted the Sewing machine to do patch jackets as part of her therapy. After 8 emails, all Makro had to say is, we'll refund you , This is Totally unexpected by me. As all I wanted was her Sewing machine. I don't want a refund. I want to see a courier guy at my gate , with the right product I ordered. Seeing as it was Makro's error, packaging the wrong item..... I expect Makro to have a sewing machine at my residence Today!. I don't want a refund!!!!!
