Terrible service

I sent my microwave in for repair two weeks ago on a Monday from Samsung canal walk after waiting a long time I called many times they said it was on sent in the Friday after I dropped it off. Samsung never had the part in the warehouse and had to be ordered, It's now two weeks and today I called Samsung where the microwave is at this morning they said it's fixed and will be at the store where I dropped it off between 12 and 13:00. I called them at 14:45 to find out if it's there and it's not. Called Samsung again and it's still in their workshop waiting for the driver to collect it. Why give a time for when it will be ready to collect when it's not there. Waste my time and airtime. I would never support Samsung if they have service like this again. No customer service as they promise to call and keep you updated but never do.
