Cherrinet Chennai worst service

Iam a regular user of cherrinet BB service for past few years. With that confidence I took yearly advance rental plan. But i regret now, why i opted for 1 year plan.. every week there is a problem! This time 10.07.2024 my service got disconnected but still on 18.07.2024 , they don’t make it ready. Very bad service. Almost every day morning and evening we used to call them and sent few emails too. But no improvement.
