Bad customer service

Bought microwave last year 2024 April its the sumsung its those 10 year warranty microwaves,early september 2025 this microwave had a fault. We took it back we waited for about 21 days with no microwave,finally we are told its ready we went to collect it. After 2 days the microwave its doing the same thing we called them and they told us to bring it back and we told them if its doing this for the third time we want refund or a new one. We waited againg with inconvenience,finally on the 29th October 2025 makro called to tell us microwave is ready for collection. We went all the way to makro Cape Gate, brought the microwave home only to find out that the glass dish that is supposed to be inside is not there. I called makro customer care and I spoke to kharida whatever the name and she told me I was suppose to check that all the microwave items are there. So my question is how do I check when the microwave is already in a box. I am not happy at all of makro service,now I must drive all the way again from Silversands to Cape Gate to look for this glass. I need assistance Angry customer
