Makro online store a nightmare

I order a microwave online on 29 March 2019 for collection latest 9 April. Today, I still do not have my order. This is my second complaint to Hellopeter regarding the same order. After the first complaint a lady called me last Thursday 18 April, to take down my address promising me free delivery because of the inconvenience. Later I received a message that my order is ready for collection at Wonderboom store. I ignored the message because I was expecting a delivery. Today, a week later, no one calls me. I called in yesterdsy and was told they will get back to me, no one did. I called today and Thandeka gave me Wonderboom store's direct line, i tried calling, its forever busy, i cant get through. What am I supposed to do now. I am taken from pillar to post. I do not know if my order is on its way to me or if it is at the Wonderboom store. I am so frustrated with Makro online store. Its a mess.
