Excitel — Excitel Broadband Services

Hi,
This Excitel broadband service (https://www.excitel.com/) is a fraud company, they have taken 4500 rs advance in January 2021 and have promised to provide seamless broadband services. It was working fine, but a month back we changed our address and asked them to shift our connection. This happened on 25 Feb 2021, and today is 18 March 2021. We are exhausted calling them, emailing them, everyone promises to fix it and then again a week passes by and nothing happens. They are not initiating a refund also and keep promising us that the issue will be solved. Still regretting taking their services.
