Good Day,
I, Sayan Das, my mobil no is XXXXXXXXX.
I want to deactive my auto deactivatecharging option and also want to remove my bank details.
I took the contract of 25Gb+2 option which I also want to disconnect. How is it possible?

Hello
welcome to our o2 Community 
Your bank details and also your way of paying your bill you can change in your Mein o2 account under Rechnung/bill.
Would this be the contract with the number ending on -663?
As you have made it via a dealer you can ask at the dealer if it is possible to cancel that contract.
Regards,
Gerrit
