If I was a smart businessman, I would fight the case and win (at any cost) just to dissuade others from taking the legal route.
This will not dissuade them. It's a matter of numbers - they have thousands of these calls going out everyday and if even 10% pays up it makes the effort very cost effective.
It has, imo, become a standard business practice to delay deactivation and then claim an extra billing period.
It is very much like the email spamming industry - just one conversion/sale makes 100 spam emails sent out very cost effective from a business point of view.
In this day and age there's no way their billing and customer depts. are not on the same page w.r.t. to your a/c.
There are loads of erp/mis/db mgmt. systems available for firms of all sizes.
Think about it, how hard is it to forward a cancellation request to their it/accounts people? This practice is nothing but disguised corporate fraud imo.
I wouldn't worry about this going to credit agencies - CIBIL, Equifax and Experian use only your loan repayments as the criteria for your credit score.
The Credit Information Companies (Regulation) Act 2005 has allowed phone service payments to be used by credit rating agencies but it's well known how unreliable it is due to poor billing practices. They would not want to deal with the large number of people asking for corrections to their score based on wrong phone/isp bills. It would only lead to increased expenses in terms of man-hours and no benefit, fiscal or otherwise for them.
Just return their equipment and get written proof of that as manoja2k suggests. It may not stop the pesky calls/emails but will at least give you peace of mind (for your exams) and you will be able to easily dismiss any and all claims they have against you.
Remember, these so called dues are not for any service provided - it is outright extortion so don't pay any amount (even 1%).
I got this directly from the TRAI website's FAQ page.
- Q 1. A consumer has made a request for termination (closure) of the service. How long has he to wait? What about rentals and other dues?
- A. The service provider shall terminate the connection within 7 days. They cannot charge rental or any other charges beyond the period of 7 days of request for closure made by the customer. Further, fresh bills shall be raised only after adjustment of the security deposit. The closure/ termination of service shall not be made conditional upon payment of dues/ bills/settlement of dispute. The outstanding amount of security deposits has to be refunded within 60 days of closure/ termination of service. In case of delay in refund beyond 60 days, a consumer is entitled to interest at the rate of 10% per annum for the number of days refund is delayed beyond 60 days.
these 2 links might help clarify the isp's obligation to you.
