Samsung warranties non existent

After Saturday this may be the last time I'll ever buy from Game stores. I live 180km from the nearest Game store and since in our small town we don't have the luxury of choosing where to buy and often we end up going to Port Elizabeth Baywest mall to buy that we cannot. I bought a few months ago a Samsung microwave and have now failed with a door error and when I took it back the manager informed me that a technician of Samsung must first look at it before I either get a new one or it's been repaired the next week. When I asked who's going to pay for the courier service or fuel to pickup the microwave the manager could not give me an direct answer either. I've contacted Samsung and they bluntly refuse to pay for the transport cost even though it's their poor quality and workmanship. I am going to take this to all social media platforms if this issue isn't resolved. I mean I had to already foot the R700 fuel bill to take it in and I've paid also for extended warranty and feel this is unfair to a customer already. It's time Store's and manufacturers do thier part for poor quality items or quality control.
