Tata Sky — recharge prob.

My subscriber id: [protected]
I am giving this complain for third time as it is not solved. I recharged on 5th feb 2019 of rs 240 which is valid for 30 days. The next recharge date should be on 7th mar 2019 as feb is having only 28 days per month. But message came as the next recharge date is on 5th mar 2019. Sending this message they are earning two days amount. It's a fraud. When i talked with the customer care people i had to count them 30 days. Still they are not convinced of recharge date. They are keep telling the recharge date should be on 5th mar 2019. If they are so concerned about the customer, should give extra day. Rather they are taking away one day. Please look after the matter. I request you to kindly call me on my registered mobile number to solve this issue asap.
Thanks.
