Yup you are right dude. They seem to have charged me at 50p/10kb and 33969 is the pulse rate. That's the only way the numbers tally. Good one.However not one CC, Dispute, or TL could explain this to me. They had no clue. All they knew was data is charged at 10p/10kb and nothing beyond. Which makes me think if they are this clueless after the event, how can they possibly appraise customers of charges and fees before the event. These guys are a nightmare. Your approach of email confirmation is the best way, but that boat has sailed for me.I do have 2-3 complaints nos. Did speak to a nodal officer earlier this evening. He had promised to call back within 2 hours. Didn't receive that call. Called back 5 hours later. Asked for the same fellow. He was busy on another call or something. but the guy who answered said my initial contact would call back soon for sure. Haven't heard from them yet.
