I had a Connect broadband connection from October 2022 . Few months ago i want to disconnect the broadband connection bcz i completed my study in Jalandhar. Then in December 19, 2023 one employee of connect broadband came and collected the modem and take 800 rupees that was my wifi bill. He said he disconnected the connection. Then in February 6, 2024 one person call me who introduced as connected broadband advocate[protected] and told me that I have due 1296 rupees in connect broadband. I If I cannot pay the money they will take legal court action . This time I clear the 1296 for settlement. And they confirm me that he disconnceted my connection. After few days he sent a directory number disconneted message. And I think the issue was resolved. But again in April 6, 2024 I give a message from connect broadband that was Mr. SOUHARDYA ADHIKARI, we have sent your details to our advocate for further proceeding at district courts Chandigarh as you didn't pay Rs. 366 along with legal charges of Rs.2500 for using connect no. 3918979 Total claim amount Rs. 2866 For settlement, contact [protected]. After few minutes from this num one person who introduced as advocate of connect broadband told I had due of 1700 rupees. If I want to settle this they give a company qr code in WhatsApp for payment otherwise they will take legal court action against me. Then I contact connect broadband offical customer care number and they told me I had due of 366. If I pay this they will give me no dues mail. Then I payment this in company website in the disconnect brodband charges portel. Then company employee told to send a mail for this message. In April 6, 2024 from connect broadband offical mail id I gave a no dues mail from their site . But today I received a same call from [protected] this number form settlement otherwise they take legal action against me. After this when I call to customer number they told there was no dues from their end. I cannot understand anything what I do. I am a college student and staying away from my home.

I want to file a case against the company, and want them to pay for all mental torture and harassment.
