AO Smith — defective product - water heater

Address:

124002

Geyser bought on 23rd december. Defective declared - 26th dec.
Till now no replacement. They say it will take 10-12 mare days

I would like to share a personal story of harassment and pain caused by ao smith sales department. A defective water heater (Reported by the company technician) bought from a dealer in gurgaon eleven days back needs another ten days to be replaced.
The answer is that 35 litre geyser is not available right now.
Has anyone heard of customer service that needs three weeks to replace a self assessed defective product.
Ao smith needs a serious internal audit or they should shut down operations here.
