[Resolved]  Voltas — complaint regarding poor customer service for a cooler

We had purchased an air cooler of 70 litres capacity on 18th june 2018 by the registered name of Pratibha Rathore. Recently the pump of the cooler became dysfunctional. Also the wheels at the base of the cooler are broken.
We registered a complaint regarding these issues with the complaint number-[protected] on 12th june 2019. We were promised that our issues would be resolved within the warranty period. But just today they cancelled our complaint which was well registered before the completion of warranty period.
Due to sheer carelessness of the service, our warranty period has ended and our issues are still unresolved. It will be appreciated if you resolve this issue as soon as possible with the warranty being extended just because of poor customer service.
