Apalling service!!!!!!!!

I made a dozen calls over 2 days and was promised by half a dozen call centre agents that a repair team would come out to fix my washing machine today and would call me by 9 am to tell me when they were arriving...it is now almost 12 noon and no word! Even tried chat on the website and no one responded. I am disappointed as previously I received good service from samsung. Will never buy one of your products again. Some of the agents i dealt with....Mamusi, Nonhlnhla, Nikita and Mark (in service tracking) and a manager, Ally (?). Finally I got a call from a repairman, Promise, who said he would be with me at 1 pm. Unbelievable incompetence...you just lost a customer...epic fail....
