Tata Teleservices — tata teleservices ltd fake tata photon plus wifi postpaid accounts, harassments by recovery agents

My tata photon number is [protected] and no outstanding bill till date 19 dec 2017 but still my mom received recovery agent call today from [protected]. Need proper justification on this and apology for the same from that recovery agent only... I already raised cancellation request for all my tata docomo number which i am using from last 3 years..

The way of talking of that agent to my mom was very bad. They have no right to harrass my parents.

That agent said that one case was filled against me.
