Broken machine, no help available from Samsung?

If I could give no rating at all, I would. After having my washing machine "fixed", it broke again 3 weeks later. After waiting a week for the parts to arrive to have it fixed, I was informed that my job was closed on the service centre's side (PMC Electronics) and according to them the job was complete. When arranging to pick up my machine I informed them of my unavailability on a certain day and asked them to come the next day. I was informed I would have to wait an additional week until they come to my area again. After asking for an exception, after all it is their fault that I had to wait so long, I was told that they cannot help me and that they would call me when they are able to come in my direction again. Bear in mind that I have already paid them for a call out fee and a new part which is not in a working condition. As a paying customer, this is the assistance I am getting. The contact person there is also extremely rude to customers. I am currently still waiting for assistance. I escalated this to Samsung South Africa who just keep reverting back to the service provider who is not helping me at all. It seems that the only route I can go is to go and purchase a new machine. I would not recommend PMC Electronics to anybody.
