Viveks — Worst customer service

Here is a frustrated customer because of vivek's service. We purchased a diaken ac 1.5 ton 6 months ago at chennai thoraipakkam and there was a pc board issue. The mechanics from viveks came and collected the board quoting 48 hours of repair time. It's been 5 working days and nothing happened. The customer care is so dumb to not even know what's going on with this issue. They sing the same song that they understand our problem and the urgency to get the repair done. The ac is still in warranty and i have a small kid at home based on which i wanted high priority attention on this simple board replacement. When something has to be done free of charge it's so difficult for these people to keep their words. Always buy in showrooms which offer proper customer care and value customers or who even know what's customer care.. Not from these electronic shops that sell lot of along with the products.
