Airtel — extra charges in bill of 5 june- 4july 2018

Address:

Sir,

I have changed my plan on 6th July 2018.
My previous plan was advance rental plan, which gets renewed in every July.
I was waiting till July to change my plan as the plan charges (999 ) per year.
I have changed my plan to 399 but still my bill generated included the advance rental charges also.
As new plan is activated the old plan should be deactivated by default as per my knowledge.
Your customer care executive said that my plan renews on 4th hence the advance rent charges are included. and now nothing can be done.
But this is for your kind information that, till July my airtel app on mobile has not facility to change the plan. But till the time i have activated new plan it allowed me to do the same. So its your app problem that it allowed me to change though the previous plan renewed for this year.
Also i have visited airtel gallery in Karvenagr, Pune in last week to change my plan they said that this can be done on my app on 5th or 6th July.
Please have a look in this matter and send me revised bill with deduction of advance rental charges.
