May I know on which plan you currently are? For e.g- If it is Rs.49_24 days then Rs.49 will be deducted from your account on E+2 days.
Your Plan Expiry: Dec 26th, 2021
Deduction Date: Dec 28th, 2021.
On 27 i.e tomorrow nothing will happen. Rs.2 deduction only if your balance is lower than your current plan.
