Tata Sky — Charging more than pack

Address:	Mumbai City, Maharashtra
Website:	tatasky

I have activated tatasky on 12/12/2015 for one month which ends on 11/01/2015 as per 30 days plan.
Again i recharged with rs 425 on 09/01/2015 with the date ends on 10/01/2016
Again i recharged with 450 with movies pack which costs 25 rs which ends on 11/02/2016 now again i recharged with 450 with dhammal and aaaaaahd channels the date of maturity should be 12/03/2016 but on my system it shows 09/04/2015 why it is so because you charge for 30 days.
