Philips India — No technician call even after 24 hours of registering a request for filter change

Address:

Pune, Maharashtra

I requested for an urgent filter change for my WP3890 water purifier. I was told by the customer care person that the technician will call in 8 working hours. It is more than 24 hours and inspite of calling customer care for more than once, no one has called back. I do not have drinking water since morning. Please help. I am a customer of Philips products since last 25 years. I dont expect this kind of service from Philips.
