Mts — Is charging me even after deactivation of postpaid no - [protected]

Address:

Kolkata, West Bengal

I have raised deactivation request on 24th June. MTS asked me clear the unbilled amount. So I cleared amount Rs 585. They said it will be temporarily deactivated and permanently deactivated on 30th June. In the month of July, I have received a bill of amount Rs 43 for billing amount between 24th June till 30th June. I have cleared that bill also. Again this month ( Aug ) I have received another bill amount Rs 53 for billing period 1st July to 3rd July. I called customer care and they are saying as per Govt. rule, they will change me 7 days additional. They have deactivated on 30th June. So they will charge 7 days rental amount for deactivate. I feel this is incorrect. They are doing false billing and saying its as per Govt. policy. Please suggest me what should I do.
