Havells India — geyser complaint taking too long to solve

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

Col ashok malhotra from noida : —
I purchased a havells 25 litre puro gyser on 03- oct 2016. On 10 dec 2018, we lodged a complaint of gyser "not working". The technician from electric beam noida visited on 10 dec itself & said that due to internal leakage, the gyser needs to be replaced from kanpur ; it will take 3-4 days. Today is 18 dec but there is no news about progress of replacement of our gyser.
Even your customer care manager here, mr. Mukesh does not answer calls or our whatsapp messages.
During this severe winter, it is causing a lot of inconvenience to us all in the family. Kindly take suitable speedy measures for the said replacement.
