Tata Docomo — Excess data usage which I didn't use

Address:

Pune, Maharashtra

I hold a tata photon plus device with a Corporate postpaid connection.

My tata photon no. is: [protected].

When I check my current usage details for current month, it shows that I have used 10GB in period between 5th jul to 20th jul. (15days)
I have hardly used my net connection during this period. I don't understand how such a high data usage is being shown.

My total monthly usage is 2-3GB.

The Reference No. is 553061.

Could you please look into this? If my data usage is not corrected at earliest, then I will be forced to discontinue with the services of
tata photon.
