My no[protected] is a corporate sim on which we got free group calling. Without intimation, the group calling became chargeable. Post that i had asked customer care to deactivate any CUG pack, feature on my number. I got a confirmation on 23rd Aug'15 stating that the pack has been deactivated. (C1-[protected]). Again for Sept month i was charged. SR#C1-[protected]. They agreed to refund the amount that time. Again for the oct bill i have been charged. I placed a written complaint on 25th nov'15 for which i didnot get any reply. Post this, i called cc support on 5th dec and they assured me that i have been wrongly charged and the amount should be refunded. But today, I have received an email from them stating that the pack is still active on my number and i have been correctly charged. In all my emails, i have specifically asked them to deactivate any other service like cug on my number, yet they keep charging me for the same. The cycle is repeated each month and i have become disappointed with the service. Once they say nothing is active and then another time they say that its still active
