Hathway — Internet service not responsive

My Internet is not working since 29 December 2021. I registered a complaint and calling hathway customer care number, but i did not get any help or response. After 4- 5 days they close my request without solving this issue.
I again fill complaint and I calling daily to hathway customer care number. they told me every times "we forward your complaint to our technical teams they will contact you soon", I daily listen these lines and no one calling me and no one is here to response.
At the time of recharge they calling me 4-5 times day and quick responsive but after that service is very poor.

please take an action soon against them as my business and job impact due to this.
