[Resolved]  DishTV — after recharge last due date showing wrong

I have the package of rs 171 per month, on dt-6.2.2018 i asked customer care about it, he told me to recharge for rs 462 for three months with gst. After it i rechared for rs 462 on dt-7.2.2018. According to it the next due date should be dt-1.5.2018 but now it is showing dt-12.4.2018 as its due date. Today on dt-9.2.2018 i talk with customer care about this problem for 15 minutes but she can't solved it up to now, so kindly solve it as soon as.
