Poor after sales service

Has anybody had the misfortune to try and get support from Samsung SA? I hd to get support with dealing with a fridge and was guided adequately through the processes to try and restore the temperature after defrosting it. Well the problem did not resolve itself and I was told that a call had been logged and on of their chosen technicians would be in contact. Well needless to say that was Saturday and it is now Tuesday and still nobody has made contact or taken my specific problem seriously. A good reason why I will never again buy any SAMSUNG product just because ot their lack of after sales service and personnel that hve no work ethics when it comes to service deivery and satisfaction when a "happy" client has been assisted and their problems solved. But I guess we shouldn't expect anything more when it comes to pride in being the best in your job because that died many years ago. Sad but unfortunately true. Luckily "Word of Mouth" is still the best way of advertising products!
