So, I got the connection on 14th of July, and I paid 400 security + 99 for prime and I was told my plan is 309 plan in which I will not be billed for 3 months, however I just got the bill for 1st sept to 30th sept for 219 rs. Not sure what is going on and further i thought once it is over , we can do pre to post recharge of 399 for 3 months again no?

I am alot confused, any postpaid users can help?
