Nothing new in this, one month old news. I tried last month when India toured Zimbabwe for 3 ODI & 3 T20 series between June 11 to June 22. I added Ten 3 channel as a-la-carte on June 11 morning and dropped on June 22 evening, so not charged for June 22 only charged for June 11 to 21 @1.67ps per day for 11 days 18.37rs. and that time cc told me now you can drop any add on or a-la-carte channels or services before the month end, lock-in policy ended yesterday means from 21 June. I did not posted same thread that time because I think I can't write more in English and admin says post/comment only in English language thats why only reading and not comments more in all post
for proof here is my tata sky's june months monthly statement
