Bosch Home India — disappointed with bosch service

There is some issue in my washing machine & service request is registered with order id: [protected] on 2 sep. This has been told that within 48 hours engineer will visit my house to resolve the problem but still nobody visited. Not only this i have again called on toll free number 3-4 times in last 1 week and every time and they ensuring me that call will be arranged with engineer by today but nothing happening. I really disappointed & frustrated now with this kind of service being provided by the company
