Reliance Communications — Poor broadband service

Address:

411036

I had availed the broadband service from Reliance communications under BAN No:-[protected]. Throughout the period of the service, the internet connection was flaky, and multiple calls to the customer care would go unresolved. During termination, I called the customer care and asked for a settlement of the final bill in lieu of poor service provided, which they agreed up on during the verbal conversation over phone. Now, after 5 years of the termination, I'm receiving notice for an advocate working for Reliance asking me to settle claims with them. I have notified them of the reason for termination and my subsequent request to the customer service, but I have not received any satisfactory answer or conclusion to this yet. Please advice on what is appropriate action for this matter.
