Tata Photon disconnected my postpaid service when I did not pay my bill. They said I used 20GB+ while my plan was 10GB/month. I told them I only used 2GB and they do not agree. They sent me my usage detail by email (session wise) in .xls format and I give below entry for 06-Sep-10. 06-Sep-10 3:58:07 PM 2 10006-Sep-10 3:58:07 PM 47 235006-Sep-10 1:31:15 PM 1 5006-Sep-10 1:31:15 PM 15 75006-Sep-10 9:04:07 PM 1 5006-Sep-10 10:17:42 PM 1 5006-Sep-10 12:36:37 PM 1 5006-Sep-10 7:16:50 PM 1 5006-Sep-10 7:16:50 PM 11 55006-Sep-10 10:21:28 AM 4 20006-Sep-10 10:21:28 AM 117 585006-Sep-10 9:16:07 PM 1 5006-Sep-10 9:16:07 PM 16 80006-Sep-10 9:26:57 PM 1 5006-Sep-10 9:26:57 PM 5 25006-Sep-10 11:46:28 AM 1 5006-Sep-10 1:41:10 PM 1 5006-Sep-10 1:44:03 PM 1 5006-Sep-10 1:44:03 PM 22 110006-Sep-10 1:06:03 PM 2 10006-Sep-10 1:06:03 PM 21 105006-Sep-10 12:53:13 PM 1 5006-Sep-10 5:13:01 PM 3 15006-Sep-10 9:36:12 PM 1 5006-Sep-10 9:36:12 PM 3 15006-Sep-10 9:40:32 PM 1 5006-Sep-10 9:40:32 PM 5 25006-Sep-10 11:30:33 AM 1 50 Does Tata Usage meter calculate 1 Day = 72 hours ????? From the above detail it does seems so. Please avoid Photon+. I bought the device for Rs. 2500/- and now have no use of it. And they want me to pay Rs. 6000+ for 1 month usage. Manish
