Den Networks — frequent internet disconnection and no resolution after multiple complaints

From last one month, i have been facing internet issues with den broadband for 4 hrs avg. Daily.
On 11th july 2020, internet was not available for almost the whole day.
Area manager never pick the phone. When i tried to customer care, no response and when i raised concern repeatedly on mail. The response was always an auto generated mail.

The service is really bad and i don't recommend this network to anyone.
