Tata Docomo — Undue demand and nasty letter

Address:

Ranchi, Jharkhand

I am a tata docomo user having two accounts[protected] and [protected]. I have paid all the bills before due date that can be checked from the track record. Recently i have received a legal notice full of nasty language asking for Rs. 555 due which was already paid. It seems the confusion was created after merger og two accounts. Tata docomo should check their records for reconciliation
